You can put this solution on YOUR website!
Given:
\n" ); document.write( "(1) 5*(4-7u) = -u - 48
\n" ); document.write( "Your first step is (usually always) to evaluate the parentheses.
\n" ); document.write( "Then (1) becomes
\n" ); document.write( "20 - 35u = -u - 48
\n" ); document.write( "Combine like terms yields
\n" ); document.write( "68 = 34u or
\n" ); document.write( "34u = 68
\n" ); document.write( "Now divide each side by 34 and obtain
\n" ); document.write( "34u/34 = 68/34 or
\n" ); document.write( "(2) u = 2
\n" ); document.write( "ALWAYS check your answer by substituting your answer into the ORIGINAL equation, (1) in this case, to see if you get equality.
\n" ); document.write( "Is [5(4 - 7*2) = -2 -48]?
\n" ); document.write( "Is [(20 - 5*14} = -50]?
\n" ); document.write( "Is [ 20 - 70) = -50]?
\n" ); document.write( "Is [-50 = -50]? Yes
\n" ); document.write( "Answer: The solution is u = 2.\r
