Algebra.Com's Answer #53752 by bucky(2189)![]() ![]() ![]() You can put this solution on YOUR website! 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. \n" ); document.write( " \n" ); document.write( " |
