8x+4x+56=1x
Multiply both sides of the equation by 8, the least common multiple of 2,8.
12x+56=1x
Combine 8x and 4x to get 12x.
12x+56-x=0
Subtract 1x from both sides.
11x+56=0
Combine 12x and -x to get 11x.
11x=-56
Subtract 56 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-56}{11}
Divide both sides by 11.
x=-\frac{56}{11}
Fraction \frac{-56}{11} can be rewritten as -\frac{56}{11} by extracting the negative sign.
