90\times 5-45\left(3x-8\right)=90\left(2x-3\right)\times \frac{7}{9}-18\left(6x-1\right)
Variable x cannot be equal to \frac{3}{2} since division by zero is not defined. Multiply both sides of the equation by 90\left(2x-3\right), the least common multiple of 2x-3,4x-6,9,10x-15.
450-45\left(3x-8\right)=90\left(2x-3\right)\times \frac{7}{9}-18\left(6x-1\right)
Multiply 90 and 5 to get 450.
450-135x+360=90\left(2x-3\right)\times \frac{7}{9}-18\left(6x-1\right)
Use the distributive property to multiply -45 by 3x-8.
810-135x=90\left(2x-3\right)\times \frac{7}{9}-18\left(6x-1\right)
Add 450 and 360 to get 810.
810-135x=70\left(2x-3\right)-18\left(6x-1\right)
Multiply 90 and \frac{7}{9} to get 70.
810-135x=140x-210-18\left(6x-1\right)
Use the distributive property to multiply 70 by 2x-3.
810-135x=140x-210-108x+18
Use the distributive property to multiply -18 by 6x-1.
810-135x=32x-210+18
Combine 140x and -108x to get 32x.
810-135x=32x-192
Add -210 and 18 to get -192.
810-135x-32x=-192
Subtract 32x from both sides.
810-167x=-192
Combine -135x and -32x to get -167x.
-167x=-192-810
Subtract 810 from both sides.
-167x=-1002
Subtract 810 from -192 to get -1002.
x=\frac{-1002}{-167}
Divide both sides by -167.
x=6
Divide -1002 by -167 to get 6.
