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
It equals x+5y simplified
-8 - 5y = 12 - 9y -8 + 4y = 12 4y = 20 y = 20/4 or 5
5y + 4 = 4y + 5 y + 4 = 5 (subtracting 4y from both sides)y = 1 (subtracting 4 from each side)
41 - y = 4y + 641 = 5y + 635 = 5y7 = y
