you can eliminate the fraction by multiplying the equation by the lowest common denominator of 3,5, and 1. Do you know what the lowest common denominator is ?
OpenStudy (anonymous):
15?
OpenStudy (anonymous):
yes. Now multiply the equation by 15. (15)2/3x + (15)4/5y = (15)20 can you do that ?
OpenStudy (anonymous):
10x+12y=300?
OpenStudy (anonymous):
