-6-56x+28=-\left(7-9x\right)-\left(x-9\right)
Use the distributive property to multiply -7 by 8x-4.
22-56x=-\left(7-9x\right)-\left(x-9\right)
Add -6 and 28 to get 22.
22-56x=-7-\left(-9x\right)-\left(x-9\right)
To find the opposite of 7-9x, find the opposite of each term.
22-56x=-7+9x-\left(x-9\right)
The opposite of -9x is 9x.
22-56x=-7+9x-x-\left(-9\right)
To find the opposite of x-9, find the opposite of each term.
22-56x=-7+9x-x+9
The opposite of -9 is 9.
22-56x=-7+8x+9
Combine 9x and -x to get 8x.
22-56x=2+8x
Add -7 and 9 to get 2.
22-56x-8x=2
Subtract 8x from both sides.
22-64x=2
Combine -56x and -8x to get -64x.
-64x=2-22
Subtract 22 from both sides.
-64x=-20
Subtract 22 from 2 to get -20.
x=\frac{-20}{-64}
Divide both sides by -64.
x=\frac{5}{16}
Reduce the fraction \frac{-20}{-64} to lowest terms by extracting and canceling out -4.
