Angle 1 and angle 5 are equal so you can set the equations equal to each other. 60 - 2x = 70 - 4x
60 + 2x = 70
2x = 10
x= 5
It’s is 6 because I added it all up and all you have to do is division
Divide by the coefficient of y.
y = (45/9)x
y = 5x
The constant of proportionality is 5.
P(G) is 26/52
P(H) is 8/52
