Question

4r+12=-16 Work shown!!! Please help

Answer 1

Answer:

$r=-7$

Step-by-step explanation:

$4r+12=-16$

Subtract 12 from both sides.

$4r=-28$

Divide both sides by 4.

$r=-7$

Check our work with substitution:

$4\cdot-7+12=-28+12=\boxed{-16}$

We see that our work is correct.

Answer 2

4r + 12 = −16

Subtract 12 from both sides.

4r = −16 − 12

Subtract 12 from −16 to get −28.

4r = −28

Divide both sides by 4.

r = -28/4

Divide −28 by 4 to get −7.

r = −7 ==> Answer
