Final answer:
To find the value of x in the equation 18 = x - 10, add 10 to both sides to isolate x, resulting in x = 28.
Step-by-step explanation:
To find the value of x in the equation 18 = x - 10, we need to isolate x on one side of the equation. This can be achieved by adding 10 to both sides of the equation. The steps are as follows:
- Add 10 to both sides of the equation: 18 + 10 = x - 10 + 10.
- Simplify both sides: 28 = x.
Therefore, the value of x is 28.
