Step-by-step solution

To solve the equation 6x2=24 6x \cdot 2 = 24 , follow these steps:

1. First, identify the operation involved. In this case, it is multiplication.

2. Divide both sides of the equation by 12 (since 6×2=12 6 \times 2 = 12 ) to isolate x x :

x=2412 x = \frac{24}{12}

3. Calculate x x :

x=2 x = 2

Final Answer

x=2 x=2

Key Points to Remember

Essential concepts to master this topic
  • Rule: Simplify products before isolating the variable
  • Technique: Calculate 6×2=12 6 \times 2 = 12 , then solve 12x=24 12x = 24
  • Check: Substitute back: 6(2)×2=12×2=24 6(2) \times 2 = 12 \times 2 = 24

Common Mistakes

Avoid these frequent errors
  • Dividing by only one factor instead of the entire product
    Don't divide 24 by just 6 to get x = 4! This ignores the factor of 2 and gives the wrong answer. Always multiply the coefficients first: 6 × 2 = 12, then divide: x = 24 ÷ 12 = 2.

FAQ

Everything you need to know about this question

Why can't I just divide 24 by 6 to get x = 4?

+

Because the equation is 6x×2=24 6x \times 2 = 24 , not 6x=24 6x = 24 ! You have two factors multiplying x: the 6 and the 2. You must account for both by calculating 6×2=12 6 \times 2 = 12 first.

What's the difference between 6x × 2 and 6 × 2x?

+

They're actually the same thing! Both equal 12x 12x due to the commutative property of multiplication. You can rearrange factors in any order: 6x×2=6×2×x=12x 6x \times 2 = 6 \times 2 \times x = 12x .

Do I need to use the distributive property here?

+

No, the distributive property is for expressions like 6(x+2) 6(x + 2) . Here you have multiplication of factors, so you simply multiply the numbers together: 6×2=12 6 \times 2 = 12 .

How do I check if x = 2 is correct?

+

Substitute x = 2 back into the original equation: 6(2)×2=12×2=24 6(2) \times 2 = 12 \times 2 = 24 . Since this equals 24, your answer is correct!

What if the equation was 6x ÷ 2 = 24 instead?

+

Then you'd have 6x2=24 \frac{6x}{2} = 24 , which simplifies to 3x=24 3x = 24 , giving x=8 x = 8 . Division and multiplication give very different results!
