x=-7
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
X equals 9.
32 + x = 259 + x = 25x = 25 - 9x = 16
If: 9x+7 = 6x+25 Then: x = 6
9x+18 = 180 9x = 180-18 9x = 162 x = 18
So 17 = 9x, making x = 1 and 8/9
9x + 9 = 135 9x = 126 x = 14
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
44 = 9x +8 36=9x 4=x
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
