Question

Solve for x and y. they both have to be the same number for each equation

Answer 1

Hey there! :D

y=2x-9

We can plug that in as y, since y is equal to 2x-9. 

5x-3(2x-9)= 23

Distribute. 

5x-6x+27= 23

-1x+27=23

Subtract 27 on both sides. 

-1x=-4

Divide both sides by -1.

x=4

Now, plug that in for y. 

y=2(4)-9

y=8-9

y=-1

 (4,-1) <== solution

I hope this helps!
