Question

Solve through the elimination method and show your work:
-x-y=-14. -3x+y=-18

Answer 1

Answer:

(- x - y = - 14)×3 = -3 x - 3y = - 42....eq (i)

.

..

- 3x - 3y = - 42

- 3x + y = - 18

__________.......subtracting

0. . + - 4y = -24

y = -24 / - 4

y = 6....eq (ii)

.

.

putting it eq 2 in eq 1 ...

- x - 6 = - 14

- x = - 14 + 6

- x = -8

x = 8....
