Lauren is 4 years older than cole. their mom is 7 years older than triple coles age. the sum of the ages of cole, lauren, and their mom is 71 years. how old is cole?

16

Step-by-step explanation:

71-4

71/3-7

=16

-2.1

Step-by-step explanation:

you equation has two negative numbers but since you have a larger number going from left to right, your answer is automatically going to be a negative answer. The method I use is plus plus keep -5.9 the same and change -3.8 to +3.8. -5.9 plus 3.8 equals  -2.1 and even if you subtracted -5.9-(-3.8) you would still get -2.1.

Hope this helps.
