8a - 15 = -3 8a = 15 - 3 8a = 12 a = 12/8 = 6/4 = 3/2
What is the answer to 11a plus 9 minus 3A equals -7?
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
2a-4y equals 3a - 8a-5y?
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
What is the answer to -8a-1 equals -23?
-8a-1=-23 (get rid of the constants on one side by adding one to both sides) -8a-1+1=-23+1 -8a=-22 (now divide both sides by -8) -8a/-8=-22/-8 (this yields...) a=-22/-8 (which is...) a=2.75
What is the answer to -8a - 6 equals 10?
-8a - 6 = 10Add 8a to each side:-6 = 8a + 10Subtract 10 from each side:-16 = 8aDivide each side by 8:-2 = aIn order to make the original statement true, ' a ' must be -2.

11a-3a =8a so 8a+9=-7 8a = -16 a=-2
2a-4y equals 3a - 8a-5y?
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
A over -4.2 - 5 equals 3 what is a?
A/-4.2 = 8A = -33.6
What is the answer to -8a-1 equals -23?
-8a-1=-23 (get rid of the constants on one side by adding one to both sides) -8a-1+1=-23+1 -8a=-22 (now divide both sides by -8) -8a/-8=-22/-8 (this yields...) a=-22/-8 (which is...) a=2.75
