Question

Solve 3/x -2y = 0 and 2/x + 5y = 19. Hence, find 'p' if y = px+3. Solve the given problem using substitution method.

Answer 1

Answer:

3/x-2y=0....|....2/x+5y=19

3/x=2y.......|...2/x=19-5y

x=3/2y.......|...2/3/2y=19-5y(puttingx

_____(1) 4y/3=19-5y =3/2y)

4y=3(19-5y)

4y=57-15y

4y+15y=57

y=57/19=3

x=3/2y___(1)

x=3/2×3

=3/6

=1/2

y=px+3

px+3=y

p×1/2+3=3(putting x=1/2;y=3)

P/2=3-3

P=0×2=0

Step-by-step explanation:

p is 0

this is the probable ans.
