Question

What is the answer to 18=6-2r

Answer 1

Answer:

$r=-6$

Step-by-step explanation:

First, we need to subtract 6 from each side, so that we can begin to isolate r.

$18=6-2r\\\\12=-2r$

Next, we can divide each side by -2

$12=-2r\\\\\frac{12}{-2} =\frac{-2r}{-2} \\\\-6=r$

Answer 2

-6 is the answer. Subtract 6 from both sides. 12=-2r, divide by -2 on each side. -6= R
