Question 1034035

What is the value of x in the solution to the system of equations below?
6x + 3y = 13
3x - y = 4

1 
(5/3)
(8/3)
(7/3)
I got 1 
<pre>MULTIPLY eq (ii) by 3. This will give you: 9x - 3y = 12 ----- eq (iii)
Now you can ADD eqs (iii) & (i) to find x. You will get 15x = 25. {{{x <> 1}}}. That much is known!
