%282%2F3%29a-3%2F4=%283%2F4%29a Start with the given equation



%2812%29%28%282%2F3%29a-3%2F4%29=%2812%29%28%283%2F4%29a%29 Multiply both sides by the LCM of 12. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)



8a-9=9a Distribute and multiply the LCM to each side



8a=9a%2B9Add 9 to both sides


8a-9a=%2B9 Subtract 9a from both sides


-a=9 Combine like terms on the left side


a=%289%29%2F%28-1%29 Divide both sides by -1 to isolate a



a=-9 Divide

Answer:
So our answer is a=-9
