Answer 1

Step-by-step explanation:

1)x=5/2 1/3

• 6x²-17x+5
• 6x²+(-15x-2x)+5
• 6x²-15x-2x+5
• 3x(2x-5)-1(2x-5)
• (2x-5)(3x-1)
• x=5/2,1/3

2)

$x = \frac{y}{2} - 5$

• let cost of ball pen be=x
• and let cost of fountain pen be=y
• cost of ball pen=(fountain pen/2)-5
• ===>
• $x = \frac{y}{2} - 5$
