What is the solution to this system of linear equations? 7x – 2y = –6

8x + y = 3

(–6, 3)
(0, 3)
(1, –5)
(15, –1)

The answer to this problem is x=36°

A satisfactory explanation:

Knowing that Line ABC is 180°, because it is straight, it is simple to take it from there.

Step 1, add the 3x and 2x together.

3x+2x=180 ---> 5x=180

Step 2, divide both sides of the equation by 5.

5x=180 ---> 5x ÷(5) =180 ÷(5) ---> x=36°

The answer is x=36°
