4\times 2x\times 7+18\times 6=9\left(x+1\right)
Multiply both sides of the equation by 36, the least common multiple of 9,2,4.
8x\times 7+18\times 6=9\left(x+1\right)
Multiply 4 and 2 to get 8.
56x+18\times 6=9\left(x+1\right)
Multiply 8 and 7 to get 56.
56x+108=9\left(x+1\right)
Multiply 18 and 6 to get 108.
56x+108=9x+9
Use the distributive property to multiply 9 by x+1.
56x+108-9x=9
Subtract 9x from both sides.
47x+108=9
Combine 56x and -9x to get 47x.
47x=9-108
Subtract 108 from both sides.
47x=-99
Subtract 108 from 9 to get -99.
x=\frac{-99}{47}
Divide both sides by 47.
x=-\frac{99}{47}
Fraction \frac{-99}{47} can be rewritten as -\frac{99}{47} by extracting the negative sign.
