Answer:

Equation: 12 + 3x = 30

Solution: x = 6

Step-by-step explanation:

12 + 3x = 30

X stands for how many hours she rented it for. You want to solve for x, so get x by itself.

12 + 3x = 30

-12           -12

---------------------

3x = 18

Divide both sides by 3

3/3x = 18/3

x = 6

makvit [3.9K]
If you need to solve this equation you can multiply the both side of equation on (-1). Like that
<span>2 = (-x);
-1·2 = (-1)·(-x)
if you multiply negative and </span><span>positive </span>you'll have negative,
if you multiply negative and <span>negative you'll have </span><span><span>positive. So
</span> 
</span>-2 = x.  or
x = -2.
The answer is -2.
