5\left(1\times 6+5\right)-18x=78
Multiply both sides of the equation by 30, the least common multiple of 6,5.
5\left(6+5\right)-18x=78
Multiply 1 and 6 to get 6.
5\times 11-18x=78
Add 6 and 5 to get 11.
55-18x=78
Multiply 5 and 11 to get 55.
-18x=78-55
Subtract 55 from both sides.
-18x=23
Subtract 55 from 78 to get 23.
x=\frac{23}{-18}
Divide both sides by -18.
x=-\frac{23}{18}
Fraction \frac{23}{-18} can be rewritten as -\frac{23}{18} by extracting the negative sign.
