Y=30
-8-5y = 12-9y 9y-5y - 12+8 4y = 20 y = 5
5y + 3 = 6y + 8 Subtract 5y from both sides: 3 = y + 8 Subtract 8 from both sides: -5 = y So y = -5
3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
It is a bigger plus. For example, 5 - (-3) = 5 + 3 = 8

3y-8+5y = 2y-39 3y+5y-2y = -39+8 6y = -31 y = -31/6
minus a minus is plus, so it's -8 + 3, which is 3 - 8, or -5
It is a bigger plus. For example, 5 - (-3) = 5 + 3 = 8
8+y = 7+5y y-5y = 7-8 -4y = -1 y = 1/4
8 + 7 + 3 - 8 = 10
5y+8=7y subtract 5y from each side , 5y+8=7y -5y -5y 8=2y /2 /2 4=y
