Solve the absolute value equation.
First subtract 5 from both sides.
|x|+5=18
|x|=13
If the absolute value of x is 13 that x equals 13 and -13. Absolute value means distance from 0.
x=13,-13
700x + 375(27 - x) = 15000
Solve for x
X=15 business class
Economy class 27-15=12
D would be the answer to your question
