You can put this solution on YOUR website!
Daren,
\n" ); document.write( "1. Put the two equations in the same format. In this case, you can skip this step because it is already done.
\n" ); document.write( "2. Make it so that, if the equations were added together, one of the variables have opposite coefficients and would cancel out. Since 2x and -2x already fulfill these requirements (if added together, the sum is 0), you can skip this step as well.
\n" ); document.write( "3. Add the two equations.
\n" ); document.write( "y = 2x - 4
\n" ); document.write( "y = -2x + 4
\n" ); document.write( "2y = 0
\n" ); document.write( "4. Solve for the variable that is not canceled out (in this case, y).
\n" ); document.write( "2y = 0
\n" ); document.write( "Divide both sides by 2: y = 0
\n" ); document.write( "5. Solve for the other variable by plugging this value into either one of the original equations.
\n" ); document.write( "y = 2x - 4
\n" ); document.write( "0 = 2x - 4
\n" ); document.write( "Add 4 to both sides of the equation: 4 = 2x
\n" ); document.write( "Divide everything by 2: 2 = x
\n" ); document.write( "6. Plug these values for x and y into coordinate form (x,y): (2,0). THEREFORE, YOUR ANSWER IS (2,0).
\n" ); document.write( "Hope I helped! Good luck! =)
