Question

For the following system, use the second equation to make a substitution for y in the first equation. 2 x + y = 5 y + 3 = 2 x

2 x + 2 x - 3 = 5
2 x + 3 - 2 x = 5
2 x + 2 x + 3 = 5

Answer 1

2x + 2x -3 = 5

Explanation:

Answer 2

2x+y=5
y+3=2x
y+3-3 = 2x-3
y= 2x -3

2x + y =5
2x + 2x -3 = 5
