This is solving systems using elimination and idk how to figure this promblem out its

\n" ); document.write( "

Elimination, as the name implies, involves the elimination of one variable in order to find the value of the other variable
\n" );
document.write( "We don't have to change any of the 2 equations since the x in the 1st equation and the x in the 2nd equation have the same,
\n" );
document.write( "but opposite-signed coefficients
\n" );
document.write( "Therefore, all that's needed is the ADDITION of the 2 equations to eliminate x
\n" );
document.write( "  x - 4y = - 19 ------- eq (i)
\n" );
document.write( "- x + 6y =   27 ------- eq (ii) 
\n" );
document.write( "      2y =    8 ------- Adding eqs (ii) & (i)
\n" );
document.write( "       y = , or \r
\n" );
document.write( "\n" );
document.write( "x - 4(4) = - 19 ------ Substituting 4 for y in eq (i)
\n" );
document.write( "x - 16   = - 19 ------ Adding 16 from both sides
\n" );
document.write( "      x  = - 19 + 16
\n" );
document.write( "      x  = 
\n" );
document.write( "That's all!! It is that simple! \n" );
document.write( "

\n" );
