Krista and Alexa played balloon darts in a school fair. Krista popped 6 balloons, which is 1 balloon less than Alexa. Complete the working equation that represents the number of balloons, b , that Alexa popped and solve the equation
b-1=?
b=? balloons
To solve the equation, we need to isolate b.
Given that "Krista popped 6 balloons, which is 1 balloon less than Alexa" we know that b = 6 + 1.
Simplifying the equation, we find that b = 7 balloons.
