Answer:
x = -17
Step-by-step explanation:
We need to subtract 15 from both sides (so that x can be by itself) and when we do so we get x = -2 - 15 = -17.
Imagine you have a pizza the whole pizza is 100%
Then the pizza is sliced on 8 equal parts that means one slice now presents a part of whole pizza 1/8 out of 8/8 in this case one slice presents 12.5% of 100% pizza.
The answer is 150 parents. Because 450/3=150
