Question

Solve using substitution: y = 22x + 10 y = 20x + 16

Answer 1

Answer:

x=3, y=76

Step-by-step explanation:

You set them equal because you plug in "y" as 22x+10 into "y=20x+16"

22x+10=20x+16

2x=6

x=3

20(3)+16=76

Answer 2

Answer:

The answer to your question is (3, 76)

Step-by-step explanation:

Data

Equation 1               y = 22x + 10

Equation 2              y = 20x + 16

Process

1.- Substitute equation 1 in equation 2

                   22x + 10 = 20x + 16

2.- Solve for x

                   22x - 20x = 16 - 10

3.- Simplify

                             2x = 6

                               x = 6/2

                               x = 3

4.- Find y

                             y = 22(3) + 10

5.- Simplify

                           y = 66 + 10

                            y = 76
