Solve for y:4 x + (4 y)/5 = 0
Bring 4 x + (4 y)/5 together using the common denominator 5:4/5 (5 x + y) = 0
Multiply both sides by 5/4:5 x + y = 0
Subtract 5 x from both sides:Answer: y = -5 x
-----------------------------
Solve for y:-3 x - y = 10
Add 3 x to both sides:-y = 3 x + 10
Multiply both sides by -1:Answer: y = -3 x - 10
