Algebra.Com's Answer #34080 by tutorcecilia(2152)![]() ![]() You can put this solution on YOUR website! pr=xp [These are multiplication problems] \n" ); document.write( "pr=xp [To solve for any of the variables, p, x, or r divide]\r \n" ); document.write( "\n" ); document.write( "For example to solve for r, divide both sides by p \n" ); document.write( "pr=xp \n" ); document.write( "pr/p=xp/p \n" ); document.write( "r=x [The p's cancel out] \n" ); document.write( ". \n" ); document.write( "Another example, to solve for x, in this case, also divide both sides by p: \n" ); document.write( "pr=xp \n" ); document.write( "pr/p=xp/p [cancel out] \n" ); document.write( "r=x \n" ); document.write( ". \n" ); document.write( "Treat the variables the same as you would treat numbers. \n" ); document.write( "To check your answers, plug the value of x (or r) back into the original equation. \n" ); document.write( " |
