Answer:
The given system of equation is
4x+
y
6
=15 ..(i)
6x−
y
8
=14 .(ii)
Multiplying equation (i) by 4 and equation (ii) by 3, we get
16x+
y
24
=60 ..(iii)
18x−
y
24
=42 (iv)
Adding (iv) and (iii), we get
34x=102⇒x=3
Putting x=3 in equation (i), we get
12+
y
6
=15⇒y=2
Hence, the solution of the given system of equations is x=3,y=2
Putting x=3,y=2 in y=px−2, we get
2=3p−2⇒p=4/3.
