Question 696568: OMG- ready to tear out my hair! Please help.
x-(8-5x)= 11(x-1)
3x +2 =8x -4 (I got -6 over -5 or 1.2- said it was wrong)
8x +5 = 20 (I got 15/8 or 1.875 - both wrong)
6(x+2)-9 = -2x (x-3) (i got -1.5 said wrong)
this one I just don't know how to do:
x+4 - x+6 equals 10 (x+4 over 5 minus x+6 over 4 equals 10)
5 4

x-1%288-5x%29=11%28x-1%29 Start with the given equation.


x-8%2B5x=11x-11 Distribute.


6x-8=11x-11 Combine like terms on the left side.


6x=11x-11%2B8 Add 8 to both sides.


6x-11x=-11%2B8 Subtract 11x from both sides.


-5x=-11%2B8 Combine like terms on the left side.


-5x=-3 Combine like terms on the right side.


x=%28-3%29%2F%28-5%29 Divide both sides by -5 to isolate x.


x=3%2F5 Reduce.
