To solve the data in the condition of setting the equations, you only need to transfer the unknown terms to one part of the equation, and the known ones to the other part.

1) -8 + x = -3.

x = -3 + 8.

x = 5.

2) x + 5 = 10.

x = 10 – 5.

x = 5.

3) x + 5 = -8.

x = -8 – 5.

x = -13.

Answer: 1) 5; 2) 5; 3) -13.
