Answer 1

Let's say the number of balloons Krista popped is represented by x, and the number of balloons Alexa popped is represented by y.
According to the given information, we know that Krista popped x balloons and Alexa popped y balloons. Together, they popped a total of 13 balloons.
So, the equation representing this information is x + y = 13.
We need to determine the number of balloons Alexa popped, which is represented by y.
