4\times 4\left(2x+5\right)+9\times 3\left(2-x\right)=18\left(5x-2\right)+6\left(10-15x\right)
Multiply both sides of the equation by 36, the least common multiple of 9,4,2,6.
16\left(2x+5\right)+9\times 3\left(2-x\right)=18\left(5x-2\right)+6\left(10-15x\right)
Multiply 4 and 4 to get 16.
32x+80+9\times 3\left(2-x\right)=18\left(5x-2\right)+6\left(10-15x\right)
Use the distributive property to multiply 16 by 2x+5.
32x+80+27\left(2-x\right)=18\left(5x-2\right)+6\left(10-15x\right)
Multiply 9 and 3 to get 27.
32x+80+54-27x=18\left(5x-2\right)+6\left(10-15x\right)
Use the distributive property to multiply 27 by 2-x.
32x+134-27x=18\left(5x-2\right)+6\left(10-15x\right)
Add 80 and 54 to get 134.
5x+134=18\left(5x-2\right)+6\left(10-15x\right)
Combine 32x and -27x to get 5x.
5x+134=90x-36+6\left(10-15x\right)
Use the distributive property to multiply 18 by 5x-2.
5x+134=90x-36+60-90x
Use the distributive property to multiply 6 by 10-15x.
5x+134=90x+24-90x
Add -36 and 60 to get 24.
5x+134=24
Combine 90x and -90x to get 0.
5x=24-134
Subtract 134 from both sides.
5x=-110
Subtract 134 from 24 to get -110.
x=\frac{-110}{5}
Divide both sides by 5.
x=-22
Divide -110 by 5 to get -22.
