Answer:

b) 5(x - 12) = 3x

Explanation:

Given expression,

→ 5/x = 3/(x - 12)

Now we have to,

→ Find the equivalent expression.

Let's find the required answer,

→ 5/x = 3/(x - 12)

Cross multiplying both sides:

→ 5(x - 12) = 3(x)

5(x - 12) = 3x

Applying Distributive property:

→ 5(x) - 5(12) = 3x

→ 5x - 60 = 3x

Solving for the value of x:

→ 5x - 3x = 60

→ 2x = 60

→ x = 60/2

→ [ x = 30 ]

Hence, the value of x is 30.

Answer: 5(x - 12) = 3x

Explanation:

We can cross-multiply to answer this question.


(5)/(x) =(3)/(x-12)

5 * (x - 12) = 3 * x

5(x - 12) = 3x
