Normally, I do not have problems when it comes to Algebra; however this certain problem has been driving me in circles.
I had to graph two linear equations, and then find their solutions. Sure, I could sub. into the equations; however, it is required I graph, unfortunetly. -__-
Any how, the equations are x+y=-6 and 2x-y=3.
So first, I had subtracted x from the equation x+y=-6, and came to the conclusion of y=-x-6 . For 2x-y=3, I subtracted 2x (which became, -y=-2x+3) and then divided everything by -1, giving me y=2x-3.
When I graphed, my solution came out to be (0,-6), which doesn't make any sense when I sub. back into it.
Any thoughts?
