76\left(3x+5\right)+17\left(11-x\right)-969=646\left(4+x\right)-16796
Multiply both sides of the equation by 1292, the least common multiple of 17,76,4,2.
228x+380+17\left(11-x\right)-969=646\left(4+x\right)-16796
Use the distributive property to multiply 76 by 3x+5.
228x+380+187-17x-969=646\left(4+x\right)-16796
Use the distributive property to multiply 17 by 11-x.
228x+567-17x-969=646\left(4+x\right)-16796
Add 380 and 187 to get 567.
211x+567-969=646\left(4+x\right)-16796
Combine 228x and -17x to get 211x.
211x-402=646\left(4+x\right)-16796
Subtract 969 from 567 to get -402.
211x-402=2584+646x-16796
Use the distributive property to multiply 646 by 4+x.
211x-402=-14212+646x
Subtract 16796 from 2584 to get -14212.
211x-402-646x=-14212
Subtract 646x from both sides.
-435x-402=-14212
Combine 211x and -646x to get -435x.
-435x=-14212+402
Add 402 to both sides.
-435x=-13810
Add -14212 and 402 to get -13810.
x=\frac{-13810}{-435}
Divide both sides by -435.
x=\frac{2762}{87}
Reduce the fraction \frac{-13810}{-435} to lowest terms by extracting and canceling out -5.
