Question 480506

{{{(matrix(2,4,

2,    -3,"|",7, 
3,     1,"|",4))}}}

Put x's just to the right of the numbers in the 1st column:

{{{(matrix(2,4,

2x,    -3,"|",7, 
3x,     1,"|",4))}}}

Put y's just to the right of the numbers in the 2nd column:

{{{(matrix(2,4,

2x,    -3y,"|",7, 
3x,     1y,"|",4))}}}

Put ="s in place of the "|"'s

{{{(matrix(2,4,

2x,    -3y,""="",7, 
3x,     1y,""="",4))}}}

Put a + sign before the 1y

{{{(matrix(2,4,

2x,    -3y,""="",7, 
3x,     ""+1y,""="",4))}}}

Erase the 1 before the y

{{{(matrix(2,4,

2x,    -3y,""="",7, 
3x,     ""+y,""="",4))}}}

Take away the spaces

{{{(matrix(2,1,

2x-3y=7, 
3x+y=4))}}}

Take away the parentheses

{{{matrix(2,1,

2x-3y=7, 
3x+y=4)}}}

Put a brace to the left:

{{{system(
2x-3y=7, 
3x+y=4)}}}

That's it.  Wasn't too hard, was it? I'll bet you could
just write it down in one step.
