Combining like terms, we get $17x-51=85$. Adding 51 to both sides we get $17x=136$. Dividing by 17 we find $x=8$. However, this does not satisfy the original equation. Therefore, we made a mistake and if we go back to the start and combine like terms differently we get $17x-16=119$, and thus $17x=135$ which gives us $x=7.9$ which rounds to $x=8$. Again, this does not satisfy the original equation, so we realize that there is no solution to this equation. However, one answer choice must be chosen, and the closest approximation of $x$ we found was 8, which round to answer choice C, though it should be noted that this answer choice is not strictly correct.

Solve the Equation 5x−85+15x−3x+34=1195 x - 85 + 15 x - 3 x + 34 = 1195x−85+15x−3x+34=119
