Answer:
The value of x = 4 when the value of y = 12
Step-by-step explanation:
∵ y α x ⇒ it is direct variation
- It means y increase when x increase
∴ y = kx ⇒ where k is a constant
- To find the value of k we will substitute the values of x
and y in the equation above
- If y = 6 when x = 2
∴ 6 = k(2) ⇒ divide two sides by 2
∴ k = 3
∴ y = 3x ⇒ equation of variation
- To find the value of x when y = 12
- Substitute the value of y in the equation of variation
∴ 12 = 3x ⇒ divide both sides by 3
∴ x = 4
* The value of x = 4 when the value of y = 12
