Question

Can someone help me please

Answer 1

y = -16

x = 2

Explanation:

-×2/ -x - 5y = 78 ➡ 2x + 10y = -156 (whole equation multiplied with -2)

then add up two equations

2x + 10y = -156

-2x + 2y = -38 (2x will be eliminated)

12y = -192

y = -16

now you can find x using the value of y

if

2x + 10y = -156 ➡ 2x -160 = -156 ➡ 2x = -156 + 160 ➡ 2x = 4
