Multiply this equation by 2 on both s...3a + b = -4<br /><br />Multiply this equation by 2 on both sides<br /><br />6a + 2b = -8 ....(new equation)<br />a - 2b = 1 ....(1st equation)<br />____________<br />7a = -7<br /><br />So, a = -1. Substitute a = -1 in any of the given two equations to find the value of b.<br /><br />All the Best.Mr. Mathhttps://www.blogger.com/profile/12962099560219120967noreply@blogger.comtag:blogger.com,1999:blog-4172814789229843414.post-20537498246194938152011-11-30T07:26:43.372+05:302011-11-30T07:26:43.372+05:30It helped alot but i don't get this one!!! i...It helped alot but i don't get this one!!! its in my math worksheet!! a-2b=1<br /> 3a+b=-4Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4172814789229843414.post-55797756233053873112011-11-13T06:19:37.094+05:302011-11-13T06:19:37.094+05:30I REALLY NEEDED TO NO THAT I NEW EXACTLY WHAT I WA...I REALLY NEEDED TO NO THAT I NEW EXACTLY WHAT I WAS DOING BEFORE THE BIG FINAL THANK YOU MATH OCEAN!!!!Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4172814789229843414.post-33709712837984700822011-03-03T07:11:28.554+05:302011-03-03T07:11:28.554+05:30This was pretty good for when you just want to pra...This was pretty good for when you just want to practice doing elimination and knowing you got it down.
