Solve the systems by substitution.
\n" ); document.write( "1st: 5x - 2y = -5
\n" ); document.write( "2nd: y - 5x = 3
\n" ); document.write( "-----------
\n" ); document.write( "Solve the 2nd for y to get:
\n" ); document.write( "3rd: y=5x+3
\n" ); document.write( "-------------
\n" ); document.write( "Substitute into the 1st to solve for \"x\", as follows:
\n" ); document.write( "5x-2(5x+3)=-5
\n" ); document.write( "5x-10x-6=-5
\n" ); document.write( "-5x=1
\n" ); document.write( "x=-1/5
\n" ); document.write( "-----------
\n" ); document.write( "Substitute into 3rd to solve for y, as follows:
\n" ); document.write( "y=5(-1/5)+3
\n" ); document.write( "y=-1+3
\n" ); document.write( "y=2
\n" ); document.write( "----------
\n" ); document.write( "Solution: x=-1/5 ; y=2
