Question

Solve the equation for y: 4x + 5y + 15 = 10.

Answer 1

4x + 5y + 15 - 10 = 0

4x + 5y + 5 = 0

5y = -4x - 5

y = (-4x - 5)/5

Answer 2

4x + 5y + 15 = 10.
1.Subtract 15 both sides.
4x+5y+15-15=10-15
4x+5y=-5
2.Subtract 4x both sides
4x+5y-4x=-5-4x
5y=-5-4x
3.Divide by 5 both sides
5y/5=(-5-4x)/5
y=(-5-4x)/5
y=-(5+4x)/5
Is that clear?
