First multiply them all by 8
2x - 1 = 7 + 4x
Subtract 2x
-1 = 7 + 2x
Subtract 7
-8 = 2x
Divide by 2
X = -4
100 because supplementary angles equal 180°
hope this helps
The math I used is probably not the quickest way, but for me, the easiest.
25*5=125 25+20=45 45*7=315 125+315=440 25*4=100 440+100=540 5+7+4=16

Answer:
y=
x+6
Step-by-step explanation:
To find the slope: 
--> 
--> 
-->
Insert into the point-slope form: (y-7)=(x+4)
Solve: y-7=x-1 --> y=+6
