Question

Please help! To solve the equation 1.75n = 7 for n, what operation must be applied to both sides in order to isolate the variable n?

Answer 1

C

Explanation:

1.75n = 7 ( to isolate n divide both sides by 1.75 )

n =
`(7)/(1.75)` = 4

Answer 2

c.) Divide by 1.75

Explanation:

Given equation:

⇒ 1.75n = 7

Here the coefficient of n which is 1.75 needs to be removed. There is only one way of doing that - by dividing both sides by 1.75.

When done so:

⇒ 1.75n/1.75 = 7/1.75

⇒ n = 4
