Question

there were some flowers in a vase. nadia put 4 more flowers in the vase. now there are 84 flowers altogether. how many flowers were in the vase to start? \square flowers

Explanation:

Step1: Define the initial number of flowers

Let the initial number of flowers be $x$.

Step2: Set up the equation

After adding 4 flowers, the total number is 84. So the equation is $x + 4 = 84$.

Step3: Solve for $x$

Subtract 4 from both sides of the equation: $x = 84 - 4$.
Calculate the right - hand side: $x = 80$.

Answer:

80
