Question 1138696

2x - 7y = -17 
5x + 3y = 19 
If your friend were going to solve this system of equations by first eliminating y, what general suggestions would you make so your friend could start on this in a systematic way?
<pre>2x - 7y = - 17 ---- eq (i)
5x + 3y = 19 ------ eq (ii)
{{{highlight_green(matrix(2,5, Multiply, eq, "(i)", by, 3, Multiply, eq, "(ii)", by, 7))}}}
