Question

solve literal equation for y: 4x - 5y= 30

Answer 1

4x - 5y = 30

4x is adding on the left, then it will subtract on the right

-5y = 30 - 4x

-5 is multiplying on the left, then it will divide on the right.

y = (30 - 4x)/(-5)

Applying distributive property:

y = 30/(-5) - 4x/(-5)

y = -6 + 4/5 x
