If 4A = I and 8A = U, show algebraically the number of I's
\n" ); document.write( "needed to equal one U.
\n" ); document.write( "

\r\n" );
document.write( "Let n = the number of I's needed to equal one U.\r\n" );
document.write( "\r\n" );
document.write( "Then\r\n" );
document.write( "\r\n" );
document.write( "nI = U\r\n" );
document.write( "\r\n" );
document.write( "Substitute 4A for I and substitute 8A for U\r\n" );
document.write( "\r\n" );
document.write( "n(4A) = 8A\r\n" );
document.write( "\r\n" );
document.write( "Solve for n:\r\n" );
document.write( "\r\n" );
document.write( "Simplifying:\r\n" );
document.write( "\r\n" );
document.write( "4nA = 8A\r\n" );
document.write( "\r\n" );
document.write( "Divide both sides by 4A\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So we need 2 I's to equal one U.\r\n" );
