Algebra.Com's Answer #254963 by jsmallt9(3758)![]() ![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "This is a proportion (one fraction equals another). So we can use cross-multiplying to solve: \n" ); document.write( "5*(4q+4) = 8*3q \n" ); document.write( "Simplifying we get: \n" ); document.write( "20q + 20 = 24q \n" ); document.write( "Get the variable on just one side (by subtracting 20q from each side: \n" ); document.write( "20 = 4q \n" ); document.write( "Divide both sides by 4: \n" ); document.write( "5 = q \n" ); document.write( "P.S. Please put multiple term numerators and denominators, like 4q+4, in parentheses! It makes the problem clearer and tutors are more likely to answer questions if they are clearly posted. \n" ); document.write( " |
