Answer 1

x + 2.6 = 10.4

x = 7.8

Explanation:

If 2.6 liters are added to x liters with the result that 10.4 liters then exist, the model is ...

2.6 +x = 10.4 . . . . . . . 2.6 added to x gives 10.4

The commutative property of addition lets you rewrite this to ...

x +2.6 = 10.4

__

Subtracting 2.6 from both sides of the equation gives its solution:

x +2.6 -2.6 = 10.4 -2.6

x = 7.8
