Answer 3

Solving the Equations

1) -2.3 - 2.9 = ?

To solve this equation, we simply subtract 2.9 from -2.3:

-2.3 - 2.9 = -5.2 2) 2.3 - (-2.9) = ?

This can be solved by subtracting -2.9 from 2.3:

2.3 - (-2.9) = 2.3 + 2.9 = 5.2 3) 3.5 - (-3.2) = ?

To solve this, we need to subtract -3.2 from 3.5:

3.5 - (-3.2) = 3.5 + 3.2 = 6.7 So, the solutions to the given equations are: 1) -2.3 - 2.9 = -5.2 2) 2.3 - (-2.9) = 5.2 3) 3.5 - (-3.2) = 6.7
