You can put this solution on YOUR website!
-s+4=7s-3
\n" ); document.write( "4+3 = 7s+s (grouping like terms, changing sign while changing side)
\n" ); document.write( "(same as adding 3 to both the sides and adding s to both the sides)
\n" ); document.write( "7=8s
\n" ); document.write( "That is 8s = 7
\n" ); document.write( "Therefore s = 7/8 (dividing by 8)
\n" ); document.write( "Verification: putting s = 7/t,
\n" ); document.write( "Lhs = -s+4 = (-7/8)+4 =(-7+32)/8= 25/8
\n" ); document.write( "RHS = 7s-3 = 7X(7/8)-3 = (49-24)/8 = 25/8 =LHS
\n" ); document.write( "Therefore our value for s is correct \n" ); document.write( "

\n" );
