2/5x + y = 12 -x + 5/2y = 6 you would multiply the second equation by 2/5, and this will cancel out the x's
OpenStudy (anonymous):
what does it mean by " which expression " ? Because I know that if you multiply the second equation by 2/5, this will cause the x's to cancel out
OpenStudy (anonymous):
the second equation, when multiplied by 2/5. is : -2/5x + y = 12/5
