8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:

X equals 9.
9x = 4x + 45 5x = 45x = 9
-20 + 9x = -17-20 + 17 = -9x-3 = -9x |: (-9)0.333... = xx = 0.333...
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
x = 5
x=9
Slope: -9
If: 12 = 9x+3 Then: 12-3 = 9x And: 9 = 9x So: x =1
9x + 4 = 6 9x = 6 -4 9x = 2 x = 2/9
