x%2F4-3x%2F2=-1%2F2 Start with the given equation



%284%29%28x%2F4-3x%2F2%29=%284%29%28-1%2F2%29 Multiply both sides by the LCM of 4. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)



x-6x=-2 Distribute and multiply the LCM to each side



-5x=-2 Combine like terms on the left side


x=%28-2%29%2F%28-5%29 Divide both sides by -5 to isolate x



x=2%2F5 Reduce

--------------------------------------------------------------
Answer:
So our answer is x=2%2F5 (which is approximately x=0.4 in decimal form)
