Answer: -13.1
Step-by-step explanation:
All you have to do is plug 4 whenever you see e and 3 for d so let’s do that:
4.7(3)-6.8(4)
*remember when there’s a number with () multiply**
so 4.7 x 3=14.1
6.8 x 4= 27.2
now out equation is: 14.1-27.2
all we do from here is subtract So you should get -13.1
