The value of R in the equation R + 14 = 39 is 25, which is option B.
;
Start with the equation R + 14 = 39 .
Subtract 14 from both sides: R = 39 − 14 .
Calculate the difference: R = 25 .
The value of R is 25 .
Explanation
Understanding the equation We are given the equation R + 14 = 39 and we need to find the value of R . This is a simple algebraic equation where we can isolate R by subtracting 14 from both sides of the equation.
Isolating R To isolate R , we subtract 14 from both sides of the equation:
R + 14 − 14 = 39 − 14
Finding the value of R Now we perform the subtraction:
R = 39 − 14 = 25
So, the value of R is 25.
Final Answer Therefore, the value of R is 25, which corresponds to option B.
Examples
Imagine you're buying a toy that costs $39. You have $14 with you. The equation R + 14 = 39 helps you calculate how much more money (R) you need to buy the toy. By solving for R, you find out exactly how much extra money you have to get.
