Step-by-step explanation:

Step 1: Simplify both sides of the equation.

a−2=

3+6a

3

a+−2=2a+1(Distribute)

a−2=2a+1

Step 2: Subtract 2a from both sides.

a−2−2a=2a+1−2a

−a−2=1

Step 3: Add 2 to both sides.

−a−2+2=1+2

−a=3

Answer:

a = -3

Step-by-step explanation:

a - 2 = (3 + 6a)/3

Divide 3 + 6a by 3.

a - 2 = 1 + 2a

Subtract 2a from both sides.

-a - 2 = 1

Add 2 to both sides.

-a = 3

Multiply the equation by -1.

a = -3.

Proof:

a - 2 = (3 + 6a)/3

Substitute variable.

-3 - 2 = (3 + 6(-3))/3

Multiply inside parenthesis.

-3 - 2 = (3 + 18)/3

Add inside parenthesis.

-3 - 2 = (-15)/3

Divide.

-3 - 2 = -5

Subtract.

-5 = -5
