Please help me !!!!!!!!!!!!!!!!

Nutka1998 [239]

Answer: x=-10, y=13

Step-by-step explanation:

$-3x+2y=56\\-5x-2y=24$

+2y-2y = 0, eliminating y is much easier. So -3x-5x = -8x and 56+24 = 80

$-8x=80\\x=-10$

Substitute x in any equations but only 1 equation (Don't substitute in both equations.)

For me, I'd substitute x in -3x+2y=50

$-3(-10)+2y=56\\30+2y=56\\2y=56-30\\2y=26\\y=13$

So the answer is x = -10, y = 13

Negative 4 equals r/20 minus 5

levacccp [35]

Answer: r = - 20

Step-by-step explanation:

$-4 = \frac{r}{20} - 5$

$\frac{r}{20} = 4-5$

$\frac{r}{20}=-1$

$\frac{r}{20}*20 = -1 * 20$

$r = -20$
