Question

1. The product of five and a number is 15

2. The sum of six and a number is 16
3. 27 divided by a number is nine
4. The product of six and a number is 72

Answer 1

Explanation:

(1)
`5x = 15`

Dividing both sides by
`5` will give us the answer:

`x = 3`

(2)
`x + 6 = 16`

Subtracting both sides by
`6` will give us the answer:

`x = 10`

(3)
`(27)/(x) = 9`

First let's multiply both sides by
`x`

`27 = 9x`

Now, let's divide both sides by
`9` to get our answer:

`x = 3`

(4)
`6x = 72`

Dividing both sides by
`6` will give us the answer:

`x = 12`
