Hey there!
This is a one-step equation, meaning that we can solve it in one step.
This is the step:
- Subtract 14 from both sides
Goal:
- To find out the value of x
Subtract 14:
x+14-14=63-14
the 14's on the left cancel:
x=49
Hence, the answer is

Hope everything is clear.
Let me know if you have any questions!
