7x+4\left(10x-15\right)-12x=4\times 4\left(2x-1\right)-3\times 3\left(2-x\right)
Multiply both sides of the equation by 12, the least common multiple of 12,3,4.
7x+40x-60-12x=4\times 4\left(2x-1\right)-3\times 3\left(2-x\right)
Use the distributive property to multiply 4 by 10x-15.
47x-60-12x=4\times 4\left(2x-1\right)-3\times 3\left(2-x\right)
Combine 7x and 40x to get 47x.
35x-60=4\times 4\left(2x-1\right)-3\times 3\left(2-x\right)
Combine 47x and -12x to get 35x.
35x-60=16\left(2x-1\right)-9\left(2-x\right)
Multiply 4 and 4 to get 16. Multiply -3 and 3 to get -9.
35x-60=32x-16-9\left(2-x\right)
Use the distributive property to multiply 16 by 2x-1.
35x-60=32x-16-18+9x
Use the distributive property to multiply -9 by 2-x.
35x-60=32x-34+9x
Subtract 18 from -16 to get -34.
35x-60=41x-34
Combine 32x and 9x to get 41x.
35x-60-41x=-34
Subtract 41x from both sides.
-6x-60=-34
Combine 35x and -41x to get -6x.
-6x=-34+60
Add 60 to both sides.
-6x=26
Add -34 and 60 to get 26.
x=\frac{26}{-6}
Divide both sides by -6.
x=-\frac{13}{3}
Reduce the fraction \frac{26}{-6} to lowest terms by extracting and canceling out 2.
