12\times 22-12\left(x+\frac{4+3}{4}\right)=4\left(4\times 3+9\right)
Multiply both sides of the equation by 12, the least common multiple of 4,3.
264-12\left(x+\frac{4+3}{4}\right)=4\left(4\times 3+9\right)
Multiply 12 and 22 to get 264.
264-12\left(x+\frac{7}{4}\right)=4\left(4\times 3+9\right)
Add 4 and 3 to get 7.
264-12x-12\times \frac{7}{4}=4\left(4\times 3+9\right)
Use the distributive property to multiply -12 by x+\frac{7}{4}.
264-12x+\frac{-12\times 7}{4}=4\left(4\times 3+9\right)
Express -12\times \frac{7}{4} as a single fraction.
264-12x+\frac{-84}{4}=4\left(4\times 3+9\right)
Multiply -12 and 7 to get -84.
264-12x-21=4\left(4\times 3+9\right)
Divide -84 by 4 to get -21.
243-12x=4\left(4\times 3+9\right)
Subtract 21 from 264 to get 243.
243-12x=4\left(12+9\right)
Multiply 4 and 3 to get 12.
243-12x=4\times 21
Add 12 and 9 to get 21.
243-12x=84
Multiply 4 and 21 to get 84.
-12x=84-243
Subtract 243 from both sides.
-12x=-159
Subtract 243 from 84 to get -159.
x=\frac{-159}{-12}
Divide both sides by -12.
x=\frac{53}{4}
Reduce the fraction \frac{-159}{-12} to lowest terms by extracting and canceling out -3.
