Step 1: Simplify both sides of the equation.
7(2-x)(41)
8(x+1)-3(x+4)= ----------------
3

Simplify: (Show steps)
-287 574
5x-4= ---------- x+ --------
3 3

Step2: Add 287/3x to both sides.
287 -287 574 287
5x-4+ -------x= ----------x+ -------+ -------x
3 3 3 3
302/3x-4=574/3

Step 3: Add 4 to both sides.

302/3x-4+4=574/3+4
302/3x=586/3

Step 4: Multiply both sides by 3/302.

(3/302)*(302/3x)=(3/302)*(586/3)

So your answer would be x= --------
