3x + 6y = -18 2y = 3x - 22 complete the second equation below so that the terms in the system align. 3x + 6y = -18 3x + 2y = -22 Which equation results when you add the equations? 8y = -40 Solve: this solution to the system is (___,___).?

Respuesta :

We have the functions:

[tex]3x+6y=-18[/tex]

And:

[tex]2y=3x-22\Rightarrow22=3x-2y[/tex]

Knwoing this, we proceed as follows:

When we sustract the second function, from the first, we will have:

[tex]3x-3x-2y-6y=22+18\Rightarrow-8y=40[/tex][tex]\Rightarrow8y=-40\Rightarrow y=-5[/tex]

If we replace in the first function we will get x = 4.

Where did you get the -3 and -36 from?
