18x+126-6\times 8x=34-9\times 5x
Multiply both sides of the equation by 18, the least common multiple of 3,9,2.
18x+126-48x=34-9\times 5x
Multiply -6 and 8 to get -48.
-30x+126=34-9\times 5x
Combine 18x and -48x to get -30x.
-30x+126=34-45x
Multiply -9 and 5 to get -45.
-30x+126+45x=34
Add 45x to both sides.
15x+126=34
Combine -30x and 45x to get 15x.
15x=34-126
Subtract 126 from both sides.
15x=-92
Subtract 126 from 34 to get -92.
x=\frac{-92}{15}
Divide both sides by 15.
x=-\frac{92}{15}
Fraction \frac{-92}{15} can be rewritten as -\frac{92}{15} by extracting the negative sign.
