x+y=113_y=x+11\r
\n" ); document.write( "\n" ); document.write( "Since y does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting y from both sides.
\n" ); document.write( "x=-y+113_y=x+11\r
\n" ); document.write( "\n" ); document.write( "Replace all occurrences of x with the solution found by solving the last equation for x. In this case, the value substituted is -y+113.
\n" ); document.write( "x=-y+113_y=(-y+113)+11\r
\n" ); document.write( "\n" ); document.write( "Remove the parentheses around the expression -y+113.
\n" ); document.write( "x=-y+113_y=-y+113+11\r
\n" ); document.write( "\n" ); document.write( "Add 11 to 113 to get 124.
\n" ); document.write( "x=-y+113_y=-y+124\r
\n" ); document.write( "\n" ); document.write( "Since -y contains the variable to solve for, move it to the left-hand side of the equation by adding y to both sides.
\n" ); document.write( "x=-y+113_y+y=124\r
\n" ); document.write( "\n" ); document.write( "Since y and y are like terms, add y to y to get 2y.
\n" ); document.write( "x=-y+113_2y=124\r
\n" ); document.write( "\n" ); document.write( "Divide each term in the equation by 2.
\n" ); document.write( "x=-y+113_(2y)/(2)=(124)/(2)\r
\n" ); document.write( "\n" ); document.write( "Simplify the left-hand side of the equation by canceling the common factors.
\n" ); document.write( "x=-y+113_y=(124)/(2)\r
\n" ); document.write( "\n" ); document.write( "Simplify the right-hand side of the equation by simplifying each term.
\n" ); document.write( "x=-y+113_y=62\r
\n" ); document.write( "\n" ); document.write( "Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is 62.
\n" ); document.write( "x=-(62)+113_y=62\r
\n" ); document.write( "\n" ); document.write( "Multiply -1 by the 62 inside the parentheses.
\n" ); document.write( "x=-62+113_y=62\r
\n" ); document.write( "\n" ); document.write( "Add 113 to -62 to get 51.
\n" ); document.write( "x=51_y=62\r
\n" ); document.write( "\n" ); document.write( "This is the solution to the system of equations.
\n" ); document.write( "x=51 (Linda)_y=62 (steve)
