\left(x-3\right)\times 7-x\times 2=\left(x-3\right)\times 6
Variable x cannot be equal to any of the values 0,3 since division by zero is not defined. Multiply both sides of the equation by x\left(x-3\right), the least common multiple of x,x-3.
7x-21-x\times 2=\left(x-3\right)\times 6
Use the distributive property to multiply x-3 by 7.
7x-21-x\times 2=6x-18
Use the distributive property to multiply x-3 by 6.
7x-21-x\times 2-6x=-18
Subtract 6x from both sides.
x-21-x\times 2=-18
Combine 7x and -6x to get x.
x-x\times 2=-18+21
Add 21 to both sides.
x-x\times 2=3
Add -18 and 21 to get 3.
x-2x=3
Multiply -1 and 2 to get -2.
-x=3
Combine x and -2x to get -x.
x=-3
Multiply both sides by -1.
