Answer:

the right system is:

2x - 5y= -5

14x+ 5y = -5

Explanation:

2x - 5y= -5 (1)

14x+ 5y = -5 (2)

(1)+(2)→ 16x=-10 then x= -10/16 = -0.625 ≈ -0.6

Now ,Using equation (1) x = -0.625 then y = 0.75 ≈ 0.8

$12(w-3)=6w
$
Distrubute the 12
$12(2w)-12(3)=6w$
$24w-36=6w$
Subract 24w from both sides
$-36=6w-24w$
$-36=-18w$
Divide both sides by -18
$w=2$
