Question

Step 1,2,3 and solution of 2x + 12 = 30

Answer 1

Step 1: Identify the variable
In the equation 2x + 12 = 30, the variable is x.

Step 2: Isolate the variable
To isolate the variable x, we need to eliminate the constant term on the left side. We can do this by subtracting 12 from both sides of the equation:
2x + 12 - 12 = 30 - 12
2x = 18

Step 3: Solve for the variable
To solve for x, divide both sides of the equation by 2:
2x/2 = 18/2
x = 9

Solution:
The solution to the equation 2x + 12 = 30 is x = 9.
