a. |5 - 7| =2
b. -3|11 - 15|=-12

|5 - 7| =2

What you want to do first is to do the equation 5-7 which is -2 but there is an absolute value sign so 2.

-3|11 - 15|=-12

For this one it is a little more difficult but all you have to do is do the equation 11-15 which is -4 but there is an absoulte value sign so 4 you then multiply 4 by -3 which is -12 bam.

it would be:
