Solve problem using substitution
2x + y = 10
y = x + 1

Answers

Answer 1
Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form: (3,4)

Equation Form:
x=3, y=4

Answer 2

Answer:

x = 3

y = 4

Step-by-step explanation:

2x +  y = 10          -----------------(I)

     y = x + 1 ---------------------(II)

Substitute y = x + 1 in equation (I)

2x + x + 1 = 10    {Combine like terms}

      3x + 1 = 10         {Subtract 1 from both sides}

             3x = 10 -1

             3x = 9 {Divide both sides by 3}

                x = 9/3

x = 3

Plugin x = 3 in equation (II)

y = 3 + 1

y = 4
