Question

Please help explanation if possible

Answer 1

Answer: x = 2 and y = -4

x + 2y = -6

x = -6-2y

Putting this in value of x in

6x + 2y = 4

6(-6-2y) + 2y = 4

-36-12y+2y = 4

-10y = 4+36

y = 40/(-10)

y = -4

Now putting this value of y in

x + 2y = -6

x + 2(-4) = -6

x -8 = -6

x = -6+8

x = 2

Therefore x = 2 and y = -4

If we put these values we can check this

x + 2y = -6

2 + 2(-4) = -6

2 -8 = -6

-6 = -6

Answer 2

Find x:
x+2y= -6 => 2y= -6-x
so substitute 2y into the equation 6x+2y=4
=> 6x-6x-x=4
x=2
find y:
6(2) + 2y= 4
y= -4

-there u go! :)
