Question

What is the value of r in the equation? -1.5(4-r)=-12

Answer 1

-4

Explanation:

-1.5 (4 - r) = -12

(4 - r) =
`(-12)/(-1.5)`

-r =
`(12)/(1.5)` - 4

r = 4 -
`(12)/(1.5)` = -4

Answer 2

12

Explanation:

We are given the following equation and we are to solve for the variable r and find its value:

`- 1 . 5 ( 4 - r ) = - 1 2`

Expanding the brackets to get:

`6-1.5r=-12`

`-1.5r=-12-6`

`- 1 . 5 r = - 1 8`

`r = \frac { - 1 8 } { - 1 . 5 }`

r = 12
