6-7\times 2=49\left(x-9\right)
Variable x cannot be equal to 9 since division by zero is not defined. Multiply both sides of the equation by 7\left(x-9\right), the least common multiple of 7x-63,x-9.
6-14=49\left(x-9\right)
Multiply -7 and 2 to get -14.
-8=49\left(x-9\right)
Subtract 14 from 6 to get -8.
-8=49x-441
Use the distributive property to multiply 49 by x-9.
49x-441=-8
Swap sides so that all variable terms are on the left hand side.
49x=-8+441
Add 441 to both sides.
49x=433
Add -8 and 441 to get 433.
x=\frac{433}{49}
Divide both sides by 49.
