12x-20=5\left(2x+1\right)
Use the distributive property to multiply 4 by 3x-5.
12x-20=10x+5
Use the distributive property to multiply 5 by 2x+1.
12x-20-10x=5
Subtract 10x from both sides.
2x-20=5
Combine 12x and -10x to get 2x.
2x=5+20
Add 20 to both sides.
2x=25
Add 5 and 20 to get 25.
x=\frac{25}{2}
Divide both sides by 2.
