Question

7x + 14 y = -14
8x + 7y=-25

Answer 1

x=4

y=1

Explanation:

7x + 14y = -14

-2/ 8x + 7y = -25 (multiple it with -2 then add it with other equation)

7x + 14y = -14

-16x -14y = 50

-9x = 36

x = -4

put the value in its place for the first equation

7 • -4 + 14y = -14

14y = -14 + 28

y= 1
