time 2nd 5/5 it become 35/5x-20
2/5x-20+35/5x-20
=37/5x-20
Idk sorry I would answer if I did but I need points to ask a question

Step-by-step explanation:
(-2,-5)➝(-2+1,-5-5)➝(-1,-10)
hope this helped have a good day
"Supplementary" angles add up to 180°.
Opposite angles are supplementary, so . . .
(12x - 4) + (19x - 2) = 180°
Clear the parentheses: 12x - 4 + 19x - 2 = 180°
Add up all the x's on the left side: 31x - 4 - 2 = 180°
Add up the plain old numbers on the left side: 31x - 6 = 180°
Add 6 to each side: 31x = 186°
Divide each side by 31 : <em>x = 6°</em>
Well ! Now that you know that x = 6° . . .
Angle EPC is (12x - 4)°
That's (12·6 - 4)°
Which is (72 - 4)°
Which is <em>68°</em>
