Question

2x+y=8;y i have no idea what theyre asking. Its solve each equation for the indicated variable

Answer 1

If solving for y: 

→ 2x + y = 8
→ Take away 2x from both sides
→ y = 8 - 2x

If solving for x:

→ 2x + y = 8
→ Take away y from both sides
→ 2x = 8 - y
→ Divide both sides by 2
→ x = $\frac{8-y}{2}$
