3\times 5\left(x-2\right)+9\times 2-\left(27+x\right)=36x+720-3\left(4-x\right)-2\left(20+3x\right)
Multiply both sides of the equation by 36, the least common multiple of 12,4,36,18.
15\left(x-2\right)+9\times 2-\left(27+x\right)=36x+720-3\left(4-x\right)-2\left(20+3x\right)
Multiply 3 and 5 to get 15.
15x-30+9\times 2-\left(27+x\right)=36x+720-3\left(4-x\right)-2\left(20+3x\right)
Use the distributive property to multiply 15 by x-2.
15x-30+18-\left(27+x\right)=36x+720-3\left(4-x\right)-2\left(20+3x\right)
Multiply 9 and 2 to get 18.
15x-12-\left(27+x\right)=36x+720-3\left(4-x\right)-2\left(20+3x\right)
Add -30 and 18 to get -12.
15x-12-27-x=36x+720-3\left(4-x\right)-2\left(20+3x\right)
To find the opposite of 27+x, find the opposite of each term.
15x-39-x=36x+720-3\left(4-x\right)-2\left(20+3x\right)
Subtract 27 from -12 to get -39.
14x-39=36x+720-3\left(4-x\right)-2\left(20+3x\right)
Combine 15x and -x to get 14x.
14x-39=36x+720-12+3x-2\left(20+3x\right)
Use the distributive property to multiply -3 by 4-x.
14x-39=36x+708+3x-2\left(20+3x\right)
Subtract 12 from 720 to get 708.
14x-39=39x+708-2\left(20+3x\right)
Combine 36x and 3x to get 39x.
14x-39=39x+708-40-6x
Use the distributive property to multiply -2 by 20+3x.
14x-39=39x+668-6x
Subtract 40 from 708 to get 668.
14x-39=33x+668
Combine 39x and -6x to get 33x.
14x-39-33x=668
Subtract 33x from both sides.
-19x-39=668
Combine 14x and -33x to get -19x.
-19x=668+39
Add 39 to both sides.
-19x=707
Add 668 and 39 to get 707.
x=\frac{707}{-19}
Divide both sides by -19.
x=-\frac{707}{19}
Fraction \frac{707}{-19} can be rewritten as -\frac{707}{19} by extracting the negative sign.
