Question

1/4x-1/6y=-2
-1/6x+1/5y=4

solve for x and y its suppose to be x equals 12 and y equals 30

need steps thanks

Answer 1

Multiply the first equation by 4 and the second by 6, and then add the two. This will eliminate the x and let you solve for y.

x - (4/6) y = -8
-x + (6/5)y = 24

(-20/30 + 36/30)y = 16
(16/30)y = 16
y = 30
