Can someone PLEASE walk me through this??


Solve by the linear combination method (with or without multiplication).


8x + 2y = 4

–4x + 3y = –10



A.

(1, 3)


B.

(2, 3)


C.

(1, 2)


D.

(1, –2)

Verified Answer :

Here, Multiply second equation by 2, 
-8x + 6y = -20

Now,Add both the equations in order to eliminate x from the expression,
8y= -16
y = -16/8
y = -2

Substitute the value in 1st equation, 
8x + 2(-2) = 4
8x = 4 + 4
x = 8 / 8
x = 1

In short, Your Answer would be Option D) (1, -2)

Hope this helps!
