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?
The problem is worked correctly at each step.
In Step 2 the problem should be 3.x + 2 = 12.
In Step 3 the problem should be 3x = 18.
In Step 4 the problem should be x = 2.

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

1.3(x + 2) = 12

2.3x + 6 = 12

3.3x = 6

4. x=2

Step-by-step explanation:

I think ok

a negative exponent is translated as follows:

so, we have
