Debbie solved the linear equation 3(x + 4) − 2 = 16 as follows: between what lines did she make an error? line 1 and line 2 line

Drupady [299]

The question is not clear because the Debbie solution lines are not visible. Nevertheless,
The correct solution for this linear equation is the following:
3(x + 4) − 2 = 16
3(x + 4) = 16 + 2
3(x + 4) = 18
(x + 4) = 18/3
(x + 4) = 6
x = 6 - 4
x = 2

$a+b+c=180, \text{ }c+e=180 \implies \\ a+b+c=c+e \implies \\ a+b=e\\$

This result is actually true for any exterior angle. The exterior angle of a triangle is equal to the sum of the two remote angles, and above is a short proof of it.
