7\left(x+1\right)-27=18x
Multiply both sides of the equation by 9.
7x+7-27=18x
Use the distributive property to multiply 7 by x+1.
7x-20=18x
Subtract 27 from 7 to get -20.
7x-20-18x=0
Subtract 18x from both sides.
-11x-20=0
Combine 7x and -18x to get -11x.
-11x=20
Add 20 to both sides. Anything plus zero gives itself.
x=\frac{20}{-11}
Divide both sides by -11.
x=-\frac{20}{11}
Fraction \frac{20}{-11} can be rewritten as -\frac{20}{11} by extracting the negative sign.
