    First subtract 1/4 from both sides. Than multiply both sides by 2 and you got your variable.

    hmm when adding or subtracting fraction you need to add or subtract the top number. what's 3 - 1 ?

    great the top number is 2 and the bottom stays the same. 2/4 Thats what you get. ok now you have x/2 = 2/4 (remember the left side you canceled the 1/4 ) now multiply both sides.

    well no it's actually (2x)/2 ... the 2s in both the top and bottom will cancel so you are left with just x now on the right side you do the same 2/4 times 2 = (2*2)/4 Whats 2 times 2?

    Thanks, find the lowest common denominator that would eliminate the fractions in this equation. 8/9x+2/3x=1/9x+45

    You might rather ask to yourself, what number should I multiply this equation with to get rid of all the fractions (denominators)

    It would be 3 if we can get 1/9 to have a 3 in the bottom but we can't because 1/9 is the most simplified version so 9 has to be the lowest.

    Well you found the number that will cancel out the fractions. Now you have to multiply 9 to both sides.

    Don't try to get a direct answer, that might not help you in the long run ;) just an advice! Straining makes you more better!
