9q%2F10-%283%2F5%29q=3%2F4-1%2F8 Start with the given equation



%2840%29%289q%2F10-%283%2F5%29q%29=%2840%29%283%2F4-1%2F8%29 Multiply both sides by the LCM of 40. This will eliminate the fractions (note: if you need help with finding the LCM, check out this solver)



36q-24q=30-5 Distribute and multiply the LCM to each side



12q=30-5 Combine like terms on the left side


12q=25 Combine like terms on the right side


q=%2825%29%2F%2812%29 Divide both sides by 12 to isolate q


--------------------------------------------------------------
Answer:
So our answer is q=25%2F12 (which is approximately q=2.08333333333333 in decimal form)
