Algebra.Com's Answer #575717 by TimothyLamb(4379)![]() ![]() You can put this solution on YOUR website! Here's a simple one: \n" ); document.write( "--- \n" ); document.write( "5/7 = 8/x \n" ); document.write( "--- \n" ); document.write( "find x: \n" ); document.write( "--- \n" ); document.write( "5/7 = 8/x \n" ); document.write( "--- \n" ); document.write( "multiply both sides by x: \n" ); document.write( "--- \n" ); document.write( "x(5/7) = x(8/x) \n" ); document.write( "5x/7 = 8x/x \n" ); document.write( "5x/7 = 8*(x/x) \n" ); document.write( "5x/7 = 8*1 \n" ); document.write( "5x/7 = 8 \n" ); document.write( "--- \n" ); document.write( "multiply both sides by 7: \n" ); document.write( "--- \n" ); document.write( "7(5x/7) = 7*8 \n" ); document.write( "5x*(7/7) = 7*8 \n" ); document.write( "5x*1 = 7*8 \n" ); document.write( "5x = 7*8 \n" ); document.write( "--- \n" ); document.write( "divide both sides by 5: \n" ); document.write( "--- \n" ); document.write( "(5x)/5 = (7*8)/5 \n" ); document.write( "(5/5)x = (7*8)/5 \n" ); document.write( "1*x = (7*8)/5 \n" ); document.write( "x = (7*8)/5 \n" ); document.write( "(7*8)/5 \n" ); document.write( "--- \n" ); document.write( "copy and paste the above expression in to this calculator: \n" ); document.write( "http://sooeet.com/math/scientific-calculator.php \n" ); document.write( "--- \n" ); document.write( "x = 11.2 \n" ); document.write( "--- \n" ); document.write( "do a few more like this, to understand the basic rules of algebraic manipulation: \n" ); document.write( "--- \n" ); document.write( "Free algebra tutoring live chat: \n" ); document.write( "http://sooeet.com/chat.php?gn=algebra \n" ); document.write( "--- \n" ); document.write( "Solve and graph linear equations: \n" ); document.write( "http://sooeet.com/math/linear-equation-solver.php \n" ); document.write( "--- \n" ); document.write( "Solve quadratic equations with quadratic formula: \n" ); document.write( "http://sooeet.com/math/quadratic-formula-solver.php \n" ); document.write( "--- \n" ); document.write( "Solve systems of linear equations up to 6-equations 6-variables: \n" ); document.write( "http://sooeet.com/math/system-of-linear-equations-solver.php \n" ); document.write( "--- \n" ); document.write( " |
