If 3x = 12, what is the value of x? (2019)
Steps
Concepts
Step 1: Start with the equation 3x = 12.
Step 2: To find x, we need to get rid of the 3 that is multiplied by x.
Step 3: We can do this by dividing both sides of the equation by 3.
Step 4: So, we divide 12 by 3: 12 / 3.
Step 5: Calculate 12 / 3, which equals 4.
Step 6: Therefore, x = 4.
Algebraic Manipulation
– The question tests the ability to isolate a variable in a simple linear equation.
