it equals 13X.
The slope is 0.
9x + 9 = 135 9x = 126 x = 14
It is 9x
9x + 5 = 5x + 179x + 5 - 5x = 179x - 5x = 4x5-4x=1717-5=1212 divided by 4 = 3x=3
x + 20 + 10x = 20 + 9x 11x + 20 = 20 + 9x Subtract 20 from both sides: 11x = 9x Subtract 9x from both sides: 2x = 0 Divide both sides by 2: x = 0
x=5.2
9x + 8 = 6x + 20(- 8 from both sides)9x = 6x + 12(- 6x from both sides)3x = 12(divide both sides by 3)x = 4
9x+3-25 = 4x-2 5x = 20 x = 4
it equals 13X.
The slope is 0.
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
