Question

How do you solve and find the ordered pairs 12x−2y=4and4y−x=−8?

Answer 1

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

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

equation (1) is multiply 2+ equation(2)

24x-4y= 8

-x+4y=-8

-----------------

23x+0y=0

23x=0

x=0

x value in equation (1)

12(0)-2y=4

-2y=4

y=-2

ordered pair (x,y)=(0,-2)
