Add like terms. "Like terms" are those with the same constellation of variables.
.. terms with variable x: 5x +3x = (5 +3)x = 8x
.. terms with no variable: -9 -20 = -29

The simplified form is 8x -29.

Hey.
The answer is (7,4).
The change of x is -6. Divide that by two(=-3) and add it to the first x-coord and you get 7.
Do the same for your y-value(change =+6/2= +3) and you'll get 4.

8x+15 = 2x+39

8x =2x+24

6x = 24

x = 24/6 = 4

angle 4 = 2(4) +39 = 8+39 = 47

angle 6 = angle 4

angle 6 = 47 degrees
