Answer:

A: 11.9

B: -9.4

Step-by-step explanation:

A: -17.4 + x = -5.6

Add 17.4 to both sides, this cancels 17.4 on the left and makes x= 11.9.

B: -5.6 + x = -15

Add 5.6 to both sides, this cancels 5.6 on the left side and makes x= -9.4.

It went down 11.9 from Monday to Tuesday
17.5 - 5.6 = 11.9
And went up 9.5 from Tuesday to Wednesday
