## Yolo4mecuite 2 years ago Solve the system of inequalities by using the substitution method. Check each solution. Show all your work. y ≤ x – 2 x + 3y ≥ 6 Solve the system of equations by using the substitution method. Check each solution. Show all your work. 3x + 2y = 6 x + 4y = -8

1. KiArUnsYu

ohhh not sure on the first one but for the second one i rearranged them so the equations looked like this: 4y=x+8 2y=3x-6 can you see how i got that?

2. Yolo4mecuite

Yes

3. KiArUnsYu

i would then try to isolate one of the Ys. 4y=x+8 would turn into y=x+2. then plug it in. 2(x+2)=3x-6 do distruibutive property 2x+4=3x-6 -2x -2x 4=x-6 +6 +6 10=x

4. Yolo4mecuite

OK!

5. KiArUnsYu

Then plug in the answer to any equation you want. you got it from there?

6. Yolo4mecuite

Yes thank you

7. KiArUnsYu

welcome.

8. Yolo4mecuite

Wait, what do you mean by pluf in the answer int o any equation?

9. Yolo4mecuite

I mena plug in the answer to any equaiton

10. Yolo4mecuite

So like 3(10) + 2y = 6 Y wasn't found?
