\left(2x+3\right)\left(7x+2\right)=\left(14x-3\right)\left(x-8\right)
Variable x cannot be equal to any of the values -\frac{3}{2},\frac{3}{14} since division by zero is not defined. Multiply both sides of the equation by \left(14x-3\right)\left(2x+3\right), the least common multiple of 14x-3,2x+3.
14x^{2}+25x+6=\left(14x-3\right)\left(x-8\right)
Use the distributive property to multiply 2x+3 by 7x+2 and combine like terms.
14x^{2}+25x+6=14x^{2}-115x+24
Use the distributive property to multiply 14x-3 by x-8 and combine like terms.
14x^{2}+25x+6-14x^{2}=-115x+24
Subtract 14x^{2} from both sides.
25x+6=-115x+24
Combine 14x^{2} and -14x^{2} to get 0.
25x+6+115x=24
Add 115x to both sides.
140x+6=24
Combine 25x and 115x to get 140x.
140x=24-6
Subtract 6 from both sides.
140x=18
Subtract 6 from 24 to get 18.
x=\frac{18}{140}
Divide both sides by 140.
x=\frac{9}{70}
Reduce the fraction \frac{18}{140} to lowest terms by extracting and canceling out 2.
