In the equation $R+14=39$, what is the value of $R$?
A) 53
B) 25
C) 24
D) 546
Answer (2)
Start with the equation R + 14 = 39 .
Isolate R by subtracting 14 from both sides: R = 39 − 14 .
Calculate the difference: R = 25 .
The value of R is 25 .
Explanation
Understanding the Problem We are given the equation R + 14 = 39 and we want to find the value of R . This is a simple algebraic equation where we need to isolate the variable R on one side of the equation.
Isolating R To isolate R , we need to subtract 14 from both sides of the equation. This maintains the equality and allows us to solve for R . So, we have:
R + 14 − 14 = 39 − 14
Calculating the Value of R Now, we perform the subtraction:
R = 39 − 14
R = 25
Final Answer Therefore, the value of R is 25.
Examples
Imagine you are buying a toy that costs $39. You have $14 with you. To find out how much more money you need, you can use the same equation: 14 + R = 39 , where R is the amount of money you still need. Solving for R gives you the additional amount you need to buy the toy. This kind of problem helps in everyday budgeting and financial planning.
To solve the equation R + 14 = 39 , we isolate R by subtracting 14 from both sides, leading to R = 25 . Thus, the value of R is 25.
