10\left(x-2\right)-6\left(x-4\right)=3\left(x+3\right)
Multiply both sides of the equation by 30, the least common multiple of 3,5,10.
10x-20-6\left(x-4\right)=3\left(x+3\right)
Use the distributive property to multiply 10 by x-2.
10x-20-6x+24=3\left(x+3\right)
Use the distributive property to multiply -6 by x-4.
4x-20+24=3\left(x+3\right)
Combine 10x and -6x to get 4x.
4x+4=3\left(x+3\right)
Add -20 and 24 to get 4.
4x+4=3x+9
Use the distributive property to multiply 3 by x+3.
4x+4-3x=9
Subtract 3x from both sides.
x+4=9
Combine 4x and -3x to get x.
x=9-4
Subtract 4 from both sides.
x=5
Subtract 4 from 9 to get 5.
