Algebra.Com's Answer #276843 by haileytucki(390)![]() ![]() You can put this solution on YOUR website! x=-3s,x=10-4s\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 -3s. \n" ); document.write( "x=-3s_(-3s)=-4s+10\r \n" ); document.write( "\n" ); document.write( "Remove the parentheses around the expression -3s. \n" ); document.write( "x=-3s_-3s=-4s+10\r \n" ); document.write( "\n" ); document.write( "Since -4s contains the variable to solve for, move it to the left-hand side of the equation by adding 4s to both sides. \n" ); document.write( "x=-3s_-3s+4s=10\r \n" ); document.write( "\n" ); document.write( "Since -3s and 4s are like terms, subtract 4s from -3s to get s. \n" ); document.write( "x=-3s_s=10\r \n" ); document.write( "\n" ); document.write( "Replace all occurrences of s with the solution found by solving the last equation for s. In this case, the value substituted is 10. \n" ); document.write( "x=-3(10)_s=10\r \n" ); document.write( "\n" ); document.write( "Multiply -3 by each term inside the parentheses. \n" ); document.write( "x=-30_s=10\r \n" ); document.write( "\n" ); document.write( "This is the solution to the system of equations. \n" ); document.write( "x=-30_s=10 \n" ); document.write( " |
