Answer:

1. -3 + 5 = 2

2. 32 - 10 = 22

3. 45 - 27 = 8 + 10

4. 17 + 56 + (-48) = 25

5. 9 - (-16) = 12 + 13

Solutions:

1. X + 5 = 2

Add -5 on both sides and cancel.

x = 2-5

x = -3

2. x - 10 = 22

Add +10 on both sides and cancel.

x = 22 + 10

x = 32

3.  X- 27 = 8 + 10

Evaluate the like terms.

x - 27 = 18

Add +27 on both sides and cancel.

x = 18 + 27

x = 45

4. 17 + x + (-48) = 25

Evaluate the first equation. DIsregard x and 25.

-48 + 17 = -31

Proceed on substitution.

-31 + x = 25

+31 on both sides and cancel.

x = 25 + 31

x = 56

5. x-(-16) = 12 + 13​

x-(-16) = 25

Negative and negative is equals to positive, therefore, x-(-16) will change sign into x+16.

x + 16 = 25

-16 on both sides and cancel.

x = 25 - 16

x = 9
