Final answer:
The student's question concerns solving for 's' in an algebraic equation. By subtracting 14 from both sides of the equation 14 + s = 28, we find that 's' equals 14.
Step-by-step explanation:
The student's question involves the basic mathematical concept of solving for an unknown variable in an algebraic equation.
Specifically, the student has presented an equation 14 + s = 28 and demonstrated the process of simplifying an equation by subtracting 2 from both sides, yielding (14+s) - 2 = 28 - 2.
This is to illustrate that the operation of addition or subtraction of the same number on the two sides of an equation does not change the equality, aligning with the properties of equality used in algebra.
Hence, both equations will lead to the same solution for 's'.
To solve for 's', we can directly solve the first equation by isolating 's' using subtraction:
14 + s = 28
s = 28 - 14
s = 14
Therefore, 's' equals 14, which is a solution that maintains the balance of the equation.
