Here's the question you clicked on:
dusty
1.) y = –x + 2 y = 3x – 1 2.) –4x + 3y = –12 –2x + 3y = –18 Will someone help me and explain this to me?
@x1xofxaxkndx can u help me pleaseeee
you want the solution??
1.) y = –x + 2 y = 3x – 1 2.) –4x + 3y = –12 –2x + 3y = –18
i so wish i could help but im dumb when it comes to this
3x + 2y = 10 ----> equation(1) 2x - 3y = 12 ----> equation(2) multiply equation(1) by -2 and equation (2) by 3 -6x - 4y = -20 6x - 9y = 36 -------------------- -13y = 16 y = -16/13 Substitute y = -16/13 into equation(1) or equation(2) to solve for x, 3x + 2y = 10 3x + 2(-16/13) = 10 3x - 32/13 = 10 39x - 32 = 130 39x = 162 x= 162/39 = 54/13
thats how to get the solution
okay so how would i graph those?
thanks anyways sweetie (: @x1xofxaxkndx
@growdabone could u help me?
i dont know how to graph
what are you wanting explained?
how to solve both of them and graph them!
www.wolframalpha.com type in both your equations and type plot you will get the graphs
i dont get graphing that well... but if u still want i can try to work with you on the problem, also freemathhelp.com will graph it for u, u gotta go to algebra and then the algebra calculator!
