Answer:

Step-by-step explanation:

5x+2y=-15

Step 1: Add -2y to both sides.

5x+2y+−2y=−15+−2y

5x=−2y−15

Step 2: Divide both sides by 5

[tex]\frac{5x}{5}[/tex]=[tex]\frac{-2y-15}{5}[/tex]

x=[tex]\frac{-2-15}{5}[/tex]

x+2y=5

Step 1: Add -x to both sides.

x+2y+−x=5+−x

2y=−x+5

Step 2: Divide both sides by 2.

[tex]\frac{2y}{2}[/tex]=[tex]\frac{-x+5}{2}[/tex]

y=[tex]\frac{-x+5}{2}[/tex]
