60\left(-\left(-3x-3\right)\right)-15\times 2\left(-5x-3\right)+12\times 5=60+20\left(12x-3\right)-60\times 9
Multiply both sides of the equation by 60, the least common multiple of 4,5,3.
60\left(-\left(-3x\right)-\left(-3\right)\right)-15\times 2\left(-5x-3\right)+12\times 5=60+20\left(12x-3\right)-60\times 9
To find the opposite of -3x-3, find the opposite of each term.
60\left(3x-\left(-3\right)\right)-15\times 2\left(-5x-3\right)+12\times 5=60+20\left(12x-3\right)-60\times 9
The opposite of -3x is 3x.
60\left(3x+3\right)-15\times 2\left(-5x-3\right)+12\times 5=60+20\left(12x-3\right)-60\times 9
The opposite of -3 is 3.
180x+180-15\times 2\left(-5x-3\right)+12\times 5=60+20\left(12x-3\right)-60\times 9
Use the distributive property to multiply 60 by 3x+3.
180x+180-30\left(-5x-3\right)+12\times 5=60+20\left(12x-3\right)-60\times 9
Multiply -15 and 2 to get -30.
180x+180+150x+90+12\times 5=60+20\left(12x-3\right)-60\times 9
Use the distributive property to multiply -30 by -5x-3.
330x+180+90+12\times 5=60+20\left(12x-3\right)-60\times 9
Combine 180x and 150x to get 330x.
330x+270+12\times 5=60+20\left(12x-3\right)-60\times 9
Add 180 and 90 to get 270.
330x+270+60=60+20\left(12x-3\right)-60\times 9
Multiply 12 and 5 to get 60.
330x+330=60+20\left(12x-3\right)-60\times 9
Add 270 and 60 to get 330.
330x+330=60+240x-60-60\times 9
Use the distributive property to multiply 20 by 12x-3.
330x+330=240x-60\times 9
Subtract 60 from 60 to get 0.
330x+330=240x-540
Multiply -60 and 9 to get -540.
330x+330-240x=-540
Subtract 240x from both sides.
90x+330=-540
Combine 330x and -240x to get 90x.
90x=-540-330
Subtract 330 from both sides.
90x=-870
Subtract 330 from -540 to get -870.
x=\frac{-870}{90}
Divide both sides by 90.
x=-\frac{29}{3}
Reduce the fraction \frac{-870}{90} to lowest terms by extracting and canceling out 30.
