Question

Solve the system by substitution y = x -2x+4y=16

Answer 1

Answer: x = 8 y = 8

Step-by-step explanation: To solve this by substitution you need to replace the y in the second equation with x (or you could replace the x with y)

-2x + 4(x) = 16

-2x + 4x = 16

2x = 16

x = 8

Because y = x, y = 8
