Step-by-step solution

To solve this problem, we'll follow these steps:

  • Step 1: Set up the equation based on the problem data.
  • Step 2: Solve for x x using the equation.
  • Step 3: Calculate the number of flowers in each bouquet.

Let's work through each step:

Step 1: Set up the equation based on the information given.
According to the problem, Hector has a total of 23+x 23+x flowers, calculated as 5×(x+3) 5 \times (x+3) flowers from the bouquets.
Thus, we set up the equation:

5(x+3)=23+x 5(x + 3) = 23 + x

Step 2: Solve for x x :

5x+15=23+x 5x + 15 = 23 + x

Subtract x x from both sides:

4x+15=23 4x + 15 = 23

Subtract 15 from both sides:

4x=8 4x = 8

Divide both sides by 4:

x=2 x = 2

Step 3: Find the number of flowers in each bouquet:

Each bouquet contains x+3 x + 3 flowers.

x+3=2+3=5 x + 3 = 2 + 3 = 5

Therefore, each bouquet contains 5 flowers.

Key Points to Remember

Essential concepts to master this topic
  • Setup: Translate word problems into algebraic equations using given relationships
  • Technique: Distribute first: 5(x+3) becomes 5x + 15
  • Check: Substitute x = 2: 5(2+3) = 25 and 23+2 = 25 ✓

Common Mistakes

Avoid these frequent errors
  • Forgetting to distribute multiplication across parentheses
    Don't solve 5(x+3) = 23+x by dividing both sides by 5 first = wrong equation 5x + 3 = (23+x)/5! This skips the distributive property completely. Always distribute multiplication before moving terms: 5(x+3) becomes 5x + 15.

FAQ

Everything you need to know about this question

Why can't I just divide both sides by 5 at the start?

+

Because you have 5(x+3), not 5x! The 5 multiplies the entire expression (x+3). You must distribute first: 5(x+3) = 5x + 15 before solving.

How do I know what the equation should be?

+

Read carefully! Hector has 5 bouquets with (x+3) flowers each, giving him 5(x+3) total flowers. This equals his total of 23+x flowers.

What does x represent versus x+3?

+

x is just a variable we solve for. x+3 represents the actual number of flowers per bouquet. So when x = 2, each bouquet has 2+3 = 5 flowers.

How can I check if my final answer makes sense?

+

Verify the word problem: 5 bouquets × 5 flowers each = 25 total flowers. Also, 23+x = 23+2 = 25 flowers. Both methods give 25 flowers total

What if I get confused by the word problem?

+
  • Identify what you know: 5 bouquets, x+3 flowers per bouquet
  • Identify the total: 23+x flowers
  • Set them equal: 5(x+3) = 23+x
