6\left(4x-5\right)-90=2\left(15-3x\right)+9x
Multiply both sides of the equation by 18, the least common multiple of 3,9,2.
24x-30-90=2\left(15-3x\right)+9x
Use the distributive property to multiply 6 by 4x-5.
24x-120=2\left(15-3x\right)+9x
Subtract 90 from -30 to get -120.
24x-120=30-6x+9x
Use the distributive property to multiply 2 by 15-3x.
24x-120=30+3x
Combine -6x and 9x to get 3x.
24x-120-3x=30
Subtract 3x from both sides.
21x-120=30
Combine 24x and -3x to get 21x.
21x=30+120
Add 120 to both sides.
21x=150
Add 30 and 120 to get 150.
x=\frac{150}{21}
Divide both sides by 21.
x=\frac{50}{7}
Reduce the fraction \frac{150}{21} to lowest terms by extracting and canceling out 3.
