I take it we need a system of equations.....
Lets eliminate a variable just to be mean :) -4x -7y =-27 (-2x+4y = 24)(-2) ----------------- -4x -7y = -27 4x -8y = -48 ------------- 0x -15y = -75 -15y = -75 y = -75/-15 = 15/3 = 5 y=5 plug it into one of the equations and solve for "x": -----------------
you wanna say something....say it :)
x=2
x = -2 i think, but I am relying on my head and its batteries are dying
