Question

Use substitution to solve each system of equations

y=3x+8
5x+2y=5

Answer 1

you plug iin the value of y into y of the second equation. 5x + 2(3x + 8) = 5. then you should get 5x + 6x + 16 = 5, and solve it from there.

Answer 2

5x+2(3x+8) = 5

5x + 6x + 16 = 5
5x + 6 x - 16 = -16

11x = -16
divide both side by 11
x = -16/11

Answer 3

no, you forgot to minus 16 from 5. the correct answer should be 11x = -11, with x = -1.
