%281%2F4%29%287%2B3x%29=-%281%2F8%29x Start with the given equation.


8%28%281%2Fcross%284%29%29%287%2B3x%29%29=8%28-%281%2Fcross%288%29%29x%29 Multiply both sides by the LCD 8 to clear any fractions.


2%287%2B3x%29=-x Multiply.


14%2B6x=-x Distribute.


6x=-x-14 Subtract 14 from both sides.


6x%2Bx=-14 Add x to both sides.


7x=-14 Combine like terms on the left side.


x=%28-14%29%2F%287%29 Divide both sides by 7 to isolate x.


x=-2 Reduce.
