Question

-За - 8 + 2а = 13what is the value of a?

Answer 1

The initial expression is:

-3a - 8 + 2a = 13

We can sum the similar terms as:

- 3a + 2a - 8 = 13

- a - 8 = 13

Adding 8 on both sides:

- a - 8 + 8 = 13 + 8

- a = 21

Multiplying by -1 on both sides:

- a * (-1) = 21*(-1)

a = - 21

Answer: -21
