8c-(c-5)>c+17
\n" ); document.write( ".
\n" ); document.write( "You can perform math operations on inequalities just as you would on an equation with the
\n" ); document.write( "exception that if in solving this problem you need to multiply or divide both sides by
\n" ); document.write( "a negative quantity, you must reverse the direction of the inequality sign.
\n" ); document.write( ".
\n" ); document.write( "Let's work this problem just as we would an equation. The goal is to get the variable c
\n" ); document.write( "on one side of the inequality and the numbers on the other side.
\n" ); document.write( ".
\n" ); document.write( "Begin by removing the parentheses. Since the parentheses are preceded by a negative
\n" ); document.write( "sign, you can remove the parentheses as long as you change the signs of the terms inside them.
\n" ); document.write( "Applying this rule results in:
\n" ); document.write( ".
\n" ); document.write( "8c - c + 5 > c + 17
\n" ); document.write( ".
\n" ); document.write( "On the left side, combine the two terms containing c to get:
\n" ); document.write( ".
\n" ); document.write( "7c + 5 > c + 17
\n" ); document.write( ".
\n" ); document.write( "Get rid of the c on the right side by subtracting c from both sides to get:
\n" ); document.write( ".
\n" ); document.write( "6c + 5 > 17
\n" ); document.write( ".
\n" ); document.write( "Get rid of the +5 on the left side by subtracting 5 from both sides:
\n" ); document.write( ".
\n" ); document.write( "6c > 12
\n" ); document.write( ".
\n" ); document.write( "Solve for c by dividing both sides by 6 the multiplier of c:
\n" ); document.write( ".
\n" ); document.write( "c > 2
\n" ); document.write( ".
\n" ); document.write( "That's the answer. The original inequality will hold for all values of c that are greater
\n" ); document.write( "than +2.
\n" ); document.write( ".
\n" ); document.write( "Notice we did not need to apply the rule that if you divide or multiply both sides by
\n" ); document.write( "a negative number you need to reverse the direction of the inequality sign.
\n" ); document.write( ".
\n" ); document.write( "Hope this clarifies the problem for you and helps you to see how to solve inequalities.
