Question

+ + = 18
+ = 9
+ + = 22
+ + = ?

Explanation:

Step1: Find the value of one apple

Let the value of one apple be \( A \). We have \( A + A + A = 18 \), so \( 3A = 18 \), then \( A=\frac{18}{3}=6 \).

Step2: Find the value of one cherry

Let the value of one cherry (the pair) be \( C \). We know \( A = 6 \) and \( C + A = 9 \), so \( C=9 - A = 9 - 6 = 3 \).

Step3: Find the value of one banana

Let the value of one banana (the pair) be \( B \). We know \( A = 6 \) and \( A + B + B = 22 \), so \( 6 + 2B = 22 \). Subtract 6 from both sides: \( 2B = 22 - 6 = 16 \), then \( B=\frac{16}{2}=8 \).

Step4: Calculate the final result

We need to find \( A + C + B \). Substitute \( A = 6 \), \( C = 3 \), \( B = 8 \): \( 6 + 3 + 8 = 17 \).
