Algebra.Com's Answer #55672 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Two variables are involved in this set of two equations ... x and y. But the problem \n" ); document.write( "already tells you that x is equal to -1. With this information you can solve for y by \n" ); document.write( "substitution. Just substitute -1 for x in the top equation. When you do the top equation \n" ); document.write( "becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "This simplifies to: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Eliminate the -2 on the left side by adding +2 to both sides to get: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Solve for y by dividing both sides by 3. This results in: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "The decimal equivalent of this is: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Hope this helps you to understand a way of solving the equation. \n" ); document.write( " |
