5y + 1 = 4y - 1 Subtract 4y from both sides of the equation. y + 1 = -1. Add 1 to both sides of the equation. y + 2 = 0 Subtract 2 from both sides of the equation. y = -2

5y + 4 = 4y + 5 y + 4 = 5 (subtracting 4y from both sides)y = 1 (subtracting 4 from each side)
They are: x = -2 and y = -1.
Here's how it is:2y + 10 = 5y - 4ySolution:2y + 10 = 1y (subtract 5y and 4y)10 = 1y - 2y10 = -1y-1(10 = -1y)y = -10
(4y - 1)(5y + 2)
x=(-5y-1)/3
