Question

How do I do this? -2(6-r)=4

Answer 1

To solve this, you need to isolate/get the variable "r" by itself in the equation:

-2(6 - r) = 4   Divide -2 on both sides

$\frac{-2(6-r)}{-2} =\frac{4}{-2}$

6 - r = -2    Subtract 6 on both sides

6 - 6 - r = -2 - 6

-r = -8       Divide -1 on both sides to get "r" by itself

$\frac{-r}{-1}=\frac{-8}{-1}$     (two negative signs cancel each other out and become positive)

r = 8

PROOF

-2(6 - r) = 4    Substitute/plug in 8 into "r"

-2(6 - 8) = 4

-2(-2) = 4

4 = 4
