You can put this solution on YOUR website!
5.85b = 8.68 + 3.68b
\n" ); document.write( "The idea is to get b by itself, usually on the left, perform algebra operations to accomplish this
\n" ); document.write( "Subtract 3.68b from both sides
\n" ); document.write( "5.85b - 3.68b = 8.68 + 3.68b - 3.68b
\n" ); document.write( "which is
\n" ); document.write( "2.17b = 8.68 + 0
\n" ); document.write( "or just
\n" ); document.write( "2.17b = 8.68
\n" ); document.write( "We want b to have a coefficient of 1, divide both sides by 2.17. divide the right side using a calc
\n" ); document.write( " $\"2.17%2F2.17\"$ b = $\"8.68%2F2.17\"$
\n" ); document.write( "which is
\n" ); document.write( "1b = 4
\n" ); document.write( "or just
\n" ); document.write( "b = 4
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Now we can prove that this is correct by replacing b with 4 in the original problem.
\n" ); document.write( "5.85b = 8.68 + 3.68b
\n" ); document.write( "5.85(4) = 8.68 + 3.68(4)
\n" ); document.write( "Using a calc we have
\n" ); document.write( "23.4 = 8.68 + 14.72
\n" ); document.write( "do the math on the right
\n" ); document.write( "23.4 = 23.4, equality!! confirms our solution of b = 4
