Final answer:
The equation representing the description 'A number x increased by 14 is 118' is x + 14 = 118. To find the value of x, subtract 14 from both sides to get x = 104.
Step-by-step explanation:
To write an equation for the description "A number x increased by 14 is 118", we set up the equation as x + 14 = 118. This is a simple linear equation where the value of x represents the unknown number. To solve for x, we subtract 14 from both sides of the equation, resulting in x = 118 - 14, which simplifies to x = 104.
