Answer:

3(x + 2) = 12

3x + 6 = 12

3x = 6

x=2

Step-by-step explanation:

Enrique was asked to solve the equation 3(x + 2) = 12. His steps are

shown.

Step 1: 3(x + 2) = 12

Step 2: 3x + 6 = 12

Step 3: 3. = 6

Step 4: x = 3

Which statement about his solution is correct?

up till step 3

The problem is worked correctly at each step.

In Step 2 the problem should be 3x + 2 = 12.

false

In Step 3 the problem should be 3x = 18.

false

In Step 4 the problem should be x = 2.

true

The statement about his solution is correct will be "In Step 4 the problem should be x = 2". Then the correct option is D.

What is the solution of the equation?

An distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The linear equation of one variable is given below.

3(x + 2) = 12

Simplify the equation, then the value of x will be

In the first step, open the bracket. Then the equation will be

3x + 6 = 12

In second step, subtract 6 from both sides, then the equation will be

3x = 12 - 6

3x = 6

In third step, divide the equation by 3, then the equation will be

x = 6/3

x = 2

Then the statement about his solution is correct will be "In Step 4 the problem should be x = 2".

Then the correct option is D.
