Solving an Equation with FractionsDate: 11/27/95 at 19:5:53 Subject: math From: Sani Salles How do I do this exercise? It is: X+5 = X-4 --- --- 4 2 - 5 Date: 12/4/95 at 1:22:28 From: Doctor Ken Subject: Re: math Hello! The most important thing to remember in doing a problem like this is to only try to focus on one part at a time. You can't do the whole problem at once! So we have this: x + 5 x - 4 ----- = ----- 4 2/5 The first thing I think I'd do is get rid of that 2/5 by multiplying the right side of the equation by 5/5. So we have x + 5 x - 4 5 ----- = ----- * --- 4 2/5 5 5(x - 4) = -------- 2 5x - 20 = ------- 2 Now you could cross-multiply to finish it off! -Doctor Ken, The Geometry Forum |
