Q
Q: If 7x = 21, what is the value of x?
Solution:
Dividing both sides by 7 gives x = 3.
Steps: 5
Show Steps
Step 1: Start with the equation 7x = 21.
Step 2: To find the value of x, we need to get x by itself. We can do this by dividing both sides of the equation by 7.
Step 3: When we divide the left side (7x) by 7, we get x.
Step 4: Now, we divide the right side (21) by 7. 21 divided by 7 equals 3.
Step 5: So, after dividing both sides, we have x = 3.
