6\left(x+2\right)-5\left(x+2\right)=10\left(x+2\right)-3\left(x+2\right)
Multiply both sides of the equation by 30, the least common multiple of 5,6,3,10.
6x+12-5\left(x+2\right)=10\left(x+2\right)-3\left(x+2\right)
Use the distributive property to multiply 6 by x+2.
6x+12-5x-10=10\left(x+2\right)-3\left(x+2\right)
Use the distributive property to multiply -5 by x+2.
x+12-10=10\left(x+2\right)-3\left(x+2\right)
Combine 6x and -5x to get x.
x+2=10\left(x+2\right)-3\left(x+2\right)
Subtract 10 from 12 to get 2.
x+2=10x+20-3\left(x+2\right)
Use the distributive property to multiply 10 by x+2.
x+2=10x+20-3x-6
Use the distributive property to multiply -3 by x+2.
x+2=7x+20-6
Combine 10x and -3x to get 7x.
x+2=7x+14
Subtract 6 from 20 to get 14.
x+2-7x=14
Subtract 7x from both sides.
-6x+2=14
Combine x and -7x to get -6x.
-6x=14-2
Subtract 2 from both sides.
-6x=12
Subtract 2 from 14 to get 12.
x=\frac{12}{-6}
Divide both sides by -6.
x=-2
Divide 12 by -6 to get -2.
