Solve: 5|x| = 45

OpenStudy (skullpatrol):

Any ideas?

OpenStudy (anonymous):

would the answer be 9

OpenStudy (anonymous):

5*9=45

OpenStudy (skullpatrol):

Yes, that value of x will make the equation true, are there any others?

OpenStudy (anonymous):

yes but keep in mind that if the number where to be negative say negative 9 the answer would still be true because eliminating the parenthesis changes the symbol
