Question 1014456
.
Solve the system of linear equations by elimination.

2x + 7y =  1     
2x - 4y = 12     
--------------------------------


<pre>
2x + 7y =  1     (1)
2x - 4y = 12     (2)

Distract (2) from (1) (both sides). You will get

7y - (-4y) = 12 - 1,

11y = -11.

What is your next step?

From this point please complete the solution yourself.
