21x-35\times 2x=135-105x
Multiply both sides of the equation by 105, the least common multiple of 5,3,7.
21x-70x=135-105x
Multiply -35 and 2 to get -70.
-49x=135-105x
Combine 21x and -70x to get -49x.
-49x+105x=135
Add 105x to both sides.
56x=135
Combine -49x and 105x to get 56x.
x=\frac{135}{56}
Divide both sides by 56.
