Algebra.Com's Answer #61592 by scianci(186)![]() ![]() ![]() You can put this solution on YOUR website! An inequality is just like an equation except instead of having a finite number of discrete solutions it has a infinite, continuous set of solutions. The mechanics of solving it are identical to what they would be if it were 2a + 7 = -5a + 28:\r \n" ); document.write( "\n" ); document.write( "1. Get the variables to one side and the constants to the other side \n" ); document.write( "2a + 5a > 28 - 7 [add 5a to both sides and subtract 7 from both sides] \n" ); document.write( "7a > 21 [combine like terms and simplify]\r \n" ); document.write( "\n" ); document.write( "2. Isolate the a by dividng both sides by 7: \n" ); document.write( " \n" ); document.write( "a > 3 [simplify]\r \n" ); document.write( "\n" ); document.write( "Any real number greater than 3 is a solution to this inequality \n" ); document.write( " |
