Can you help me solve (x=-2y+1)
\n" ); document.write( " (x=y-5)\r
\n" ); document.write( "\n" ); document.write( "x=-2y+1 ----(1)
\n" ); document.write( "x= y-5 ----(2)
\n" ); document.write( "(1)-(2) gives
\n" ); document.write( "(x-x)=[(-2y)-(y)]+[(1)-(-5)] (observing that the coefficient of x in both the equations is the same 1 and hence by subtraction the x variable is eliminated)
\n" ); document.write( "0= -3y+ 6
\n" ); document.write( "3y = 6
\n" ); document.write( "y = 6/3 = 2
\n" ); document.write( "y=2 in (1) gives x = -2y+1 = -2X(2)+1 =-4+1 = -3
\n" ); document.write( "Answer:x=-3 and y = 2
\n" ); document.write( "Verification: Putting x=-3 and y = 2 in the other equation x= y-5 ----(2)
\n" ); document.write( "LHS= x = -3 and RHS= y-5 = 2-5 =-3 = LHS.
\n" ); document.write( "Therefore our values are correct.\r
