Question

If 5p-7q=70, what is the value of p/7-q/5?

A. 1/35
B. 1
C. 2
D. 35

Answer 1

2

Step-by-step explanation:

Take a common factor of 5p and 7q such that it becomes in the form p/7 and q/5 :

⇒ Here, we'll take 35 (7 × 5 = 35)

⇒
`35 ( (p)/(7) - (q)/(5) ) = 70`

⇒
`\ (p)/(7) - (q)/(5) = (70)/(35)`

⇒
`\ (p)/(7) - (q)/(5)` = 2

Answer 2

`5p - 7q = 70 \\ (1)/(35) (5p - 7q) = (70)/(35) = 2 \\ (p)/(7) - (q)/(5) = 2`
