Question

use the substitution method to solve the system of equations. 2x+y=8 y=-x+5​

Answer 1

Answer:

$x=\frac{-1}{3} y+\frac{5}{3}$

Step-by-step explanation:

Step 1: Add x to both sides.

2x+y+x=−x+5+x

3x+y=5

Step 2: Add -y to both sides.

3x+y+−y=5+−y

3x=−y+5

Step 3: Divide both sides by 3.

3x /3 = −y+5 /3
