How to solve world problem ?</h3>
Endeavor to understand the question, analyze it and interpret it into equation.
Given that Helen's age is multiples of 4. Next year it'll be a multiple of 3. Helen's older brother is now 19.
This means Helen current age is multiple of 4 and next year it will be a multiple of 3. Also, Helen's age is less than 19
The two available numbers that fit this analysis and less than 19 are 8 and 9. 8 is multiple of 4. 8 + 1 = 9 which is multiple of 3
Therefore, Helen is 8 years old now

The answer is 4
A = 1 so, 6x1 is 6 - 2 = 4
The answer is actually 2 because you have 0.5x (I think that's what it's supposed to be) and 6x.
Answer:
4(3x-y)
Step-by-step explanation:
Given:
To factor this kind of expression, first, find the common factor.
Notice that in the expression, we have both same (3x-y). Therefore, (3x-y) is our factor.
Let u = 3x-y
Change u back to 3x-y:
Therefore, the factored expression is 4(3x-y).
