To find the value of [tex]\( R \)[/tex] in the equation [tex]\( R + 14 = 39 \)[/tex], follow these steps:
1. Start with the given equation:
[tex]\[
R + 14 = 39
\][/tex]
2. To isolate [tex]\( R \)[/tex], you need to get rid of the constant term on the left side of the equation. You can do this by subtracting 14 from both sides of the equation. This step maintains the equality.
Subtract 14 from both sides:
[tex]\[
R + 14 - 14 = 39 - 14
\][/tex]
3. Simplify both sides. On the left side, [tex]\( 14 - 14 \)[/tex] equals 0, and on the right side, [tex]\( 39 - 14 \)[/tex] simplifies to:
[tex]\[
R = 25
\][/tex]
Thus, the value of [tex]\( R \)[/tex] is [tex]\( 25 \)[/tex].
The correct answer is:
B. 25
