Which choice is a solution to the system of equations?

To solve this system, I would use substitution.

Since our first equation tells us that y = 2x - 3, we can substitute a

2x - 3 in for the y in our second equation to get 2x - 3 - 9 = -x.

Simplifying on the left we get 2x - 12 = -x.

Moving the 2x to the right, we have -12 = -3x.

Now divide both sides by -3 and we have 4 = x.

To find y, plug 4 back into either one of the original equations.

I'll go with the first one.

So we have y = 2(4) - 3.

Solving from here, we find that y = 5.

So the solution to this system is (4,5).

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
