Answer:
37
Step-by-step explanation:
2-digit number: 10x + y
y = x + 4
20x + 2y = 10y + x + 1
8y = 19x - 1
8x + 32 = 19x - 1
11x = 33
x = 3

2(x+7) 2x + 20
- 2 =
x+4
2x + 8
Answer:
x = 0
Step-by-step explanation:
2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing
2(x+7) would be 2x+14
4(2x+8) would be 8x+32
2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms
2x and 2x can be combined on the left side
x and 8x can be combined on the right side
4x + 14 + 20 - 2 = x + 8x + 32
4x + 32 = 9x + 32 you can now solve this equation
start by subtracting 4x on both sides
32 = 5x +32 now subtract 32 on both sides
0 = 5x so x = 0
Answer:
x = 0
2(x+7) 2x + 20 - 2 = x+4(2x + 8) start by distributing
2(x+7) would be 2x+14
4(2x+8) would be 8x+32
2x+14 x 2x + 20 - 2 = x + 8x + 32 now combine like terms
2x and 2x can be combined on the left side
x and 8x can be combined on the right side
4x + 14 + 20 - 2 = x + 8x + 32
4x + 32 = 9x + 32 you can now solve this equation
start by subtracting 4x on both sides
32 = 5x +32 now subtract 32 on both sides
0 = 5x so x = 0

How can we use variables and equations to help us
solve problems?
Answer:
Variables help show the numbers and equation show the numbers
Step-by-step explanation:
Answer:
If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

Find the equation of the line that passes through (4,4) and is parallel to
y=3x+4 Leave your answer in the form y=mx+c
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + y + 2 = 0 ( subtract 3x + 2 from both sides )
y = - 3x - 2 ← in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, thus
y = - 3x + c ← is the partial equation
To find c substitute (3, - 4) into the partial equation
- 4 = - 9 + c ⇒ c = - 4 + 9 = 5
y = - 3x + 5 ← equation of line in form y = mx + c
The equation of line which parallel to given line is, [tex]y=3x-8[/tex]
Slope intercept form:The equation of line in slope intercept form is,
[tex]y=mx+c[/tex]
Where m is slope of line and c is y-intercept.
Equation of line given that,
[tex]y=3x+4[/tex]
So that, slope of line is [tex]3[/tex]
We have to find the equation of the line that passes through (4,4) and is parallel to given lines.
Since, slope of all parallel lines are same.
Equation of required line is,
[tex]y=3x+c[/tex]
Substitute point (4,4) in above line.
[tex]4=12+c\\\\c=4-12=-8[/tex]
So that, equation of line become,
[tex]y=3x-8[/tex]

Please help me with this one please, I've been having trouble figuring this one out.
Answer:
y = - 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (2, - 3)
m = [tex]\frac{-3-5}{2+2}[/tex] = [tex]\frac{-8}{4}[/tex] = - 2
The line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = - 2x - 1 ← equation of line
