9x-20=3\left(2x+5\right)
Variable x cannot be equal to -\frac{5}{2} since division by zero is not defined. Multiply both sides of the equation by 2x+5.
9x-20=6x+15
Use the distributive property to multiply 3 by 2x+5.
9x-20-6x=15
Subtract 6x from both sides.
3x-20=15
Combine 9x and -6x to get 3x.
3x=15+20
Add 20 to both sides.
3x=35
Add 15 and 20 to get 35.
x=\frac{35}{3}
Divide both sides by 3.
