Question

question 9 of 10 what is the solution to this equation? $x + 13 = 34$ a. $x = 27$ b. $x = 19$ c. $x = 21$ d. $x = 47$

Explanation:

Step1: Isolate the variable \( x \)

To solve for \( x \) in the equation \( x + 13 = 34 \), we need to subtract 13 from both sides of the equation. This is based on the subtraction property of equality, which states that if we subtract the same number from both sides of an equation, the equality still holds.
So, we have:
\( x + 13 - 13 = 34 - 13 \)

Step2: Simplify both sides

Simplifying the left side, \( x + 13 - 13 \) simplifies to \( x \) because \( 13 - 13 = 0 \).
Simplifying the right side, \( 34 - 13 = 21 \).

Answer:

C. \( x = 21 \)
