Question & Answer
Find the solution of x – 13 = 25 and verify using substitution
1 Answer
Verified archiveTo solve the equation ( x – 13 = 25 ), we can isolate ( x ) by adding 13 to both sides:
[
x – 13 + 13 = 25 + 13
]
This simplifies to:
[
x = 38
]
Now, let’s verify the solution by substituting ( x ) back into the original equation:
[
38 – 13 = 25
]
Calculating the left side gives:
[
25 = 25
]
This is true, so the correct answer is:
A. x = 38; 38 – 13 = 25; 25 = 25
