3\left(2x+3-\left(5x-7\right)\right)=\left(6x+11\right)\left(-8\right)
Variable x cannot be equal to -\frac{11}{6} since division by zero is not defined. Multiply both sides of the equation by 3\left(6x+11\right), the least common multiple of 6x+11,3.
3\left(2x+3-5x+7\right)=\left(6x+11\right)\left(-8\right)
To find the opposite of 5x-7, find the opposite of each term.
3\left(-3x+3+7\right)=\left(6x+11\right)\left(-8\right)
Combine 2x and -5x to get -3x.
3\left(-3x+10\right)=\left(6x+11\right)\left(-8\right)
Add 3 and 7 to get 10.
-9x+30=\left(6x+11\right)\left(-8\right)
Use the distributive property to multiply 3 by -3x+10.
-9x+30=-48x-88
Use the distributive property to multiply 6x+11 by -8.
-9x+30+48x=-88
Add 48x to both sides.
39x+30=-88
Combine -9x and 48x to get 39x.
39x=-88-30
Subtract 30 from both sides.
39x=-118
Subtract 30 from -88 to get -118.
x=\frac{-118}{39}
Divide both sides by 39.
x=-\frac{118}{39}
Fraction \frac{-118}{39} can be rewritten as -\frac{118}{39} by extracting the negative sign.
