Answer:
(x + 60 + 30) * 2 = 200
(x + 90) * 2 = 200 multiply 2 inside parentheses
2x + 180 = 200 move 180 to the other side with changing it's sign
2x = 20 multiply by 2
x = 10 here is the answer
Step-by-step explanation:

part of it is what makes it true.
The reason being is that the only thing that won’t make
true is when the denominator equals 0, because anything divided by 0 is undefined. So, when you plug
for x in the denominator you get:
. The
part just turns into 7, and 7 - 7 is 0. So you don’t want x to equal
.
<u>So the answer is A:</u>
,
±
There you go my friend!
