\left(4x-14\right)\left(4x-1\right)+10\left(x+2\right)=\left(2x-7\right)\left(8x-3\right)+10\left(2x-7\right)\left(-\frac{13}{10}\right)
Variable x cannot be equal to \frac{7}{2} since division by zero is not defined. Multiply both sides of the equation by 10\left(2x-7\right), the least common multiple of 5,2x-7,10.
16x^{2}-60x+14+10\left(x+2\right)=\left(2x-7\right)\left(8x-3\right)+10\left(2x-7\right)\left(-\frac{13}{10}\right)
Use the distributive property to multiply 4x-14 by 4x-1 and combine like terms.
16x^{2}-60x+14+10x+20=\left(2x-7\right)\left(8x-3\right)+10\left(2x-7\right)\left(-\frac{13}{10}\right)
Use the distributive property to multiply 10 by x+2.
16x^{2}-50x+14+20=\left(2x-7\right)\left(8x-3\right)+10\left(2x-7\right)\left(-\frac{13}{10}\right)
Combine -60x and 10x to get -50x.
16x^{2}-50x+34=\left(2x-7\right)\left(8x-3\right)+10\left(2x-7\right)\left(-\frac{13}{10}\right)
Add 14 and 20 to get 34.
16x^{2}-50x+34=16x^{2}-62x+21+10\left(2x-7\right)\left(-\frac{13}{10}\right)
Use the distributive property to multiply 2x-7 by 8x-3 and combine like terms.
16x^{2}-50x+34=16x^{2}-62x+21-13\left(2x-7\right)
Multiply 10 and -\frac{13}{10} to get -13.
16x^{2}-50x+34=16x^{2}-62x+21-26x+91
Use the distributive property to multiply -13 by 2x-7.
16x^{2}-50x+34=16x^{2}-88x+21+91
Combine -62x and -26x to get -88x.
16x^{2}-50x+34=16x^{2}-88x+112
Add 21 and 91 to get 112.
16x^{2}-50x+34-16x^{2}=-88x+112
Subtract 16x^{2} from both sides.
-50x+34=-88x+112
Combine 16x^{2} and -16x^{2} to get 0.
-50x+34+88x=112
Add 88x to both sides.
38x+34=112
Combine -50x and 88x to get 38x.
38x=112-34
Subtract 34 from both sides.
38x=78
Subtract 34 from 112 to get 78.
x=\frac{78}{38}
Divide both sides by 38.
x=\frac{39}{19}
Reduce the fraction \frac{78}{38} to lowest terms by extracting and canceling out 2.
