You don't have a graph there so idk if im right but i think its (0,2) and (3,1) plz tell me if im wrong :)
Answer:
The solutions for the equation 
are 
.
Step-by-step explanation:
To find the solutions for the equation you must:
X=number of adults, y= number of students
x+y=12
18x+12y=162
You can simplify the second equation by dividing by six: 3x+2y=27
Rearrange the first equation: y= 12-x. Plug y into the simplified second equation:
3x+2(12-x)=27
3x-2x+24=27
x=3.
Plug the now known x value into y=12-x. So y= 9.
Therefore, there are 3 adults and 9 students.

= 5x - 10 + 2x
= 7x -10
answer
</span>7x -10
