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.

Answer:

Option 3rd is correct

a = -6

Step-by-step 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
