Answer:

x=3, y = 15

Step-by-step explanation:

We can solve using the substitution method by substituting 3x+6 for y...

x+3x+6=18

Combine like terms

4x+6=18

4x=12

x=3

Now we need to find y. We can plug 3 in for x to solve for y...

y=3(3)+6

y=9+6

y=15

(x,y)=(3,15)

If x=-6, which inequality is true ??<br>​
Gelneren [198K]

<em>Answer:</em>

The inequality that is true is -5 - 3x > 10.

<em>Step-by-step explanation:</em>

if x = -6

we can subtitution x to every inequality, so :

-5 - 3x > 10

-5 - 3(-6) > 10

-5 - (-18) > 10

-5 + 18 > 10

13 > 10 [true]

-3 - 5x < -14

-3 - 5(-6) < -14

-3 - (-30) < -14

-3 + 30 < -14

27 < -14 [false]

2 - x < -3

2 - (-6) < -3

2 + 6 < -3

8 < -3 [false]

So if x=-6, inequality true is -5 - 3x > 10.
