Explanation:

x

Fraction bar/divide ---> --- = 7

5

1. Isolate the variable since it says dividing by 5 we must do the inverse operation which is multiplying by 5 to cancel them out. We are multiplying by 5 on one side of equation so we must multiply on the other side too. When a number is next to parenthesis it means to multiply the 2 numbers.

x

(5) -- = 7 (5)

5

x = 35

Check:

35

---- = 7

5

7 = 7

True statement.

Answer 2

`x=35`

Explanation:

Given the following question:


`(x)/(5) =7`

When x is the numerator of the fraction you multiply each side by the denominator in order to isolate the variable.


`(x)/(5) =7`

`(5x)/(5) =x`

`7*5=35`

`x=35`

Hope this helps.
