Question

The following equation is an example of a literal equation.2(x + a) = 4bA. Solve the given equation for the variable a. In your final answer, include all of your workB. In two or more complete sentences, explain the specific process that you followed in solving for a.

Answer 1

A) The given equation is expressed as

2(x + a) = 4b

To solve for a, the first step is to divide both sides of the equation by 2. It becomes

2(x + a)/2 = 4b/2

x + a = 2b

We would subtract x from both sides of the equation. It becomes

x - x + a = 2b - x

a = 2b - x

B) The processes used include division which was followed by subtraction
