\left(12x+16\right)\left(3+2x\right)+20\left(5x+2\right)=20\left(3x+4\right)+\left(3x+4\right)\left(8x+7\right)
Variable x cannot be equal to -\frac{4}{3} since division by zero is not defined. Multiply both sides of the equation by 20\left(3x+4\right), the least common multiple of 5,4+3x,20.
68x+24x^{2}+48+20\left(5x+2\right)=20\left(3x+4\right)+\left(3x+4\right)\left(8x+7\right)
Use the distributive property to multiply 12x+16 by 3+2x and combine like terms.
68x+24x^{2}+48+100x+40=20\left(3x+4\right)+\left(3x+4\right)\left(8x+7\right)
Use the distributive property to multiply 20 by 5x+2.
168x+24x^{2}+48+40=20\left(3x+4\right)+\left(3x+4\right)\left(8x+7\right)
Combine 68x and 100x to get 168x.
168x+24x^{2}+88=20\left(3x+4\right)+\left(3x+4\right)\left(8x+7\right)
Add 48 and 40 to get 88.
168x+24x^{2}+88=60x+80+\left(3x+4\right)\left(8x+7\right)
Use the distributive property to multiply 20 by 3x+4.
168x+24x^{2}+88=60x+80+24x^{2}+53x+28
Use the distributive property to multiply 3x+4 by 8x+7 and combine like terms.
168x+24x^{2}+88=113x+80+24x^{2}+28
Combine 60x and 53x to get 113x.
168x+24x^{2}+88=113x+108+24x^{2}
Add 80 and 28 to get 108.
168x+24x^{2}+88-113x=108+24x^{2}
Subtract 113x from both sides.
55x+24x^{2}+88=108+24x^{2}
Combine 168x and -113x to get 55x.
55x+24x^{2}+88-24x^{2}=108
Subtract 24x^{2} from both sides.
55x+88=108
Combine 24x^{2} and -24x^{2} to get 0.
55x=108-88
Subtract 88 from both sides.
55x=20
Subtract 88 from 108 to get 20.
x=\frac{20}{55}
Divide both sides by 55.
x=\frac{4}{11}
Reduce the fraction \frac{20}{55} to lowest terms by extracting and canceling out 5.
