Question

What is the value of a in the equation a = 2 3a 10? 12 6 −6 −12

Answer 1

Option 3rd is correct

a = -6

Explanation:

Given the equation:

`a = 2+3a+10`

Like terms are those terms which have same variable to the same power.

Combine like terms we have;

`a = 12+3a`

Subtract 3a from both sides we have;

`a-3a = 12+3a-3a`

Simplify:

`-2a = 12`

Divide both sides by 2 we have;

`a = -6`

therefore, the value of a is, -6

Answer 2

If you would like to solve the equation a = 2 + 3a + 10, you can do this using the following steps:

a = 2 + 3a + 10
-2 - 10 = 3a - a
-12 = 2a /2
a = -6

The correct result would be -6.
