7 0

Answer:

x=0;y=-2

Step-by-step explanation:

multiply first equation by 6: 18x-24y=48

Subtract 2nd equation from 1st: -19y=38

y=-2

Sub into 1st equation: 3x-4(-2)=8

3x+8=8

3x=0

Therefore, x=0;y=-2

What is the answer for 144=-12(x+5) must show work
miskamm [114]

Answer:

<h2>x = -17</h2>

Step-by-step explanation:

-12(x+5)=144\qquad\text{divide both sides by (-12)}\\\\\dfrac{-12(x+5)}{-12}=\dfrac{144}{-12}\\\\x+5=-12\qquad\text{subtract 5 from both sides}\\\\x+5-5=-12-5\\\\x=-17
