It is -14x - 13.
9x-5x=4x, 7/4=1.75, x=1.75
9x+7
9x + 7 = 5x + 35Subtract 5x from each side of the equation:4x + 7 = 35Subtract 7 from each side:4x = 28Divide each side by 4:x = 7
4x+7=9x+7 -5x=0 x=0
14x is the sum of 5x and 9x
14x + 3
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
x = 5
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
It simplifies to: 12 -6x
-4
5x + 7 + 4x = 79 9x + 7 = 79 (Gather the x's) 9x = 72 (Take away 7 from each side) x = 8 (Divide each side by 9 to get the answer)
