2 - 8(-7 + x)+ 5x
First use the distributive property
2-8(-7)-8(x)+5x
2+56-8x+5x
Next combine like terms
2+56=58
-8x+5x=-3x
you get
58-3x
Hope it helped=)

2 - 8(-7 + x)+ 5x
=> 2 + 56 - 8x + 5x => - 3x + 58 ....... Answer
If you wish the solution of the eqn
2 - 8(-7 + x)+ 5x < 333 then we have -
- 3x + 58 < 333
-3x < 333 - 58
- 3x < 275
3x > - 275
x > - 275/3

2 - 8(- 7 + x) + 5 < 333
2 + 56 - 8x + 5 < 333
63 - 8x < 333
- 8x < 270
x < - 135/4
Answer: x < - 135/4 or - 33 3/4
