>2X-3/3=3x+2/5 That is mistyped because when typing a fraction all on one line using this " / " for a fraction bar, you must enclose all numerators and denominators within parentheses which contain more than just one number or just one letter. So you should have typed this: (2x-3)/3 = (3x+2)/5 You wouldn't need to put the denominators within parentheses because they are just one number each. Parentheses aren't necessary when written on two lines with horizontal fraction bars, like this: 2x-3 3x+2 ------ = ------ 3 5 Anyway, the idea is to clear of fractions. The LCD of 3 and 5 is 15, so multiply both sides by 15. That is, put 15 over 1, like this: 15 ----· 1 then put this in front of every term on both sides: 15 2x-3 15 3x+2 ----·------ = ----·------ 1 3 1 5 Now cancel the 3 into the 15 on the left, getting 5. Cancel 5 into 15 on the right, getting 3. 5 3152x-3153x+2 ----·------ = ----·------ 13151 1 Now you must place parentheses around the 2x-3, like this (2x-3), and also around the 3x+2, like this (3x+2) and your equation becomes 5(2x-3) = 3(3x+2) Can you finish from there? Answer: x = 21 Edwin
