Question

-3x + y = 10

solve the equation for Y

Answer 1

All you need to do is add 3x to both sides. Then, on the left, you are just left with y.

y = 3x+ 10

Answer 2

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-3*x+y-(10)=0

Pull out like factors :

-3x + y - 10 = -1 • (3x - y + 10)
