Question

solve the simultaneous equations:
-4x - 2y = -12
4x+8y=-24

Answer 1

Answer:

x = 6 y = -6

Step-by-step explanation:

-4x - 2y = -12. --------(1)

4x+8y=-24. --------(2)

_____________

(1)+(2)

6y = -36

y = -36/6

y= -6

sub y = -6 in (1)

-4x -2(-6) = -12

-4x = -12-12

x = -24/-4

x =6
