x = -2
Explanation:
First, you want to multiply both sides by 35. This eliminates the need for a denominator.
Next, factor out your terms and simplify on the left side.
Next, subtract 19 from each side.
Finally, divide by 8 to get your answer.
There is an optional step. If you want to, plug -2 into the equation to check your answer.
