14\left(8-2x\right)+6\left(5-2x\right)+168=210-42\left(8x-6\right)+21
Multiply both sides of the equation by 42, the least common multiple of 3,7,2.
112-28x+6\left(5-2x\right)+168=210-42\left(8x-6\right)+21
Use the distributive property to multiply 14 by 8-2x.
112-28x+30-12x+168=210-42\left(8x-6\right)+21
Use the distributive property to multiply 6 by 5-2x.
142-28x-12x+168=210-42\left(8x-6\right)+21
Add 112 and 30 to get 142.
142-40x+168=210-42\left(8x-6\right)+21
Combine -28x and -12x to get -40x.
310-40x=210-42\left(8x-6\right)+21
Add 142 and 168 to get 310.
310-40x=210-336x+252+21
Use the distributive property to multiply -42 by 8x-6.
310-40x=462-336x+21
Add 210 and 252 to get 462.
310-40x=483-336x
Add 462 and 21 to get 483.
310-40x+336x=483
Add 336x to both sides.
310+296x=483
Combine -40x and 336x to get 296x.
296x=483-310
Subtract 310 from both sides.
296x=173
Subtract 310 from 483 to get 173.
x=\frac{173}{296}
Divide both sides by 296.
