What are your answers?
it's not two equations, it's like one all together
Yeah, x= .75 isnt right. Solve for y in one of the equations, then plug that expression in for y into the other. Then you can solve for x
okay, one sec then
You did that wrong. The purpose is to have one variable to solve for. You still have 2. lets solve for y in the second equation y=3.25x+14 now plug the expression into the other equation for y 2.5x-3(3.25x+14)=-13 now solve for x
2.5x-9.75x-42=-13 -7.25x=29 x=?
i had the math right, for some reason though, i put -13+42=27 :S oops. thanks! is that all i have to do?
What did you get for x? dont you wanna solve for y also?
just plug it into the second equation to get y? :/
If you're doing systems of equations i assume you should know how to solve a simple equation...i did all of it except one step.. x=29/-7.25 x=-4
Input -4 into one of the equations for x and then solve for y
thank youu (:
