Final answer:
Yu Yan sells 10 t-shirts and Henry sells 16 t-shirts.
Step-by-step explanation:
Let's assign variables to represent the number of t-shirts that Yu Yan and Henry sell.
Let's say the number of t-shirts Yu Yan sells is x and the number of t-shirts Henry sells is x + 6.
We know that the total number of t-shirts sold is 26.
So, we can write an equation using the given information:
x + (x + 6) = 26
This equation represents that the sum of the number of t-shirts Yu Yan sold and the number of t-shirts Henry sold is equal to 26.
We can solve this equation to find the values of x and x + 6.
- Simplify the equation: 2x + 6 = 26
- Isolate the variable x: 2x = 20
- Divide both sides by 2: x = 10
So, Yu Yan sells 10 t-shirts (x = 10) and Henry sells 16 t-shirts (x + 6 = 16).
