Question 1011631
.
<pre>
3x + 5y = 7   (1)
2x + 4y = 6   (2)

Multiply equation (1) by 2. Multiply the equation (2) by -3 and then add. 
You will get (after canceling like terms) a single equation for y:

10y - 12y = 14 - 18,   or

-2y = -4.

Hence, y = 2. Now from (1) you can find x = {{{(7-5y)/3}}} = {{{(7-5*2)/3}}} = {{{(7-10)/3}}} = {{{-3/3}}} = -1.

<U>Answer</U>. x = -1, y = 2.

I didn't solve the system #1, because I am not sure you wrote it correctly.
