12x-20-5\left(2x+7\right)=1
Use the distributive property to multiply 4 by 3x-5.
12x-20-10x-35=1
Use the distributive property to multiply -5 by 2x+7.
2x-20-35=1
Combine 12x and -10x to get 2x.
2x-55=1
Subtract 35 from -20 to get -55.
2x=1+55
Add 55 to both sides.
2x=56
Add 1 and 55 to get 56.
x=\frac{56}{2}
Divide both sides by 2.
x=28
Divide 56 by 2 to get 28.
