You can put this solution on YOUR website!

document.write( "(1, -2) 4x-3Y=10 or 4*1+3*2=10 4+6=10  Yes
\n" );
document.write( "x+4y=7 or 1+4*(-2)=7   1+(-8)=7  No:  -7 ≠ 7
\n" );
document.write( "Might Check Your Sign in EQ II:  would yield the solution (1,-2) , y = -2 and x = 1
\n" );
document.write( "I.  4x-3y = 10
\n" );
document.write( "II. x+4y = 7              ||Signs SO important to the Solution
\n" );
document.write( "   4x-3y = 10
\n" );
document.write( "  -4x-16y = -28
\n" );
document.write( "     -19y = -18
\n" );
document.write( "        y = 18/19 = 0.947368421052632  and  x = 3.21052631578947

document.write( "(1,-2) is a Pt on the fist line, not the 2nd line. The Solution for this system
\n" );
document.write( "of Two EQ, is as You found: x = 3.21052631578947, y = 0.947368421052632 \r
