Step-by-step explanation:
The correct answer is 0.6
Answer:

Step-by-step explanation:
Eqn. 1 ----> 4y = x
Eqn. 2 ----> 5x-10y = -50
(Simplifying eqn.2 further)


(Substituting the value of x from eqn. 1)



Now, substituting the value of y in eqn. 1 ,

Use the point-slope formula, y-y1=m(x-x1) to find the equation of the line
The answer is y=3x-1. Hope this helps!
