Help please... I really didn’t understand this lesson.

Answer:
7(14)-11=87
2(14)-3=25
5(14)-2=68
Step-by-step explanation:
Ight Homie, lemme help you out.
To start, add (7x-11) + (2x-3) + (5x-2)
That should get you (14x-16)
Then set up the equation
14x-16=180
180 is the sum of the triangle angles. (if i said that right)
Then solve for x
14x-16=180
+16 +16
14x=196 Divide
((14x)/14)=196/14
x should equal 14.
Then replace x with 14
7(14)-11=87
2(14)-3=25
5(14)-2=68
I hope this helps. Stay safe Homie!
