(5x^4 – 3x^3 + 6x) – ( 3x^3 + 11x^2 – 8x)
= (5x^4 – 3x^3 + 6x) + ( -3x^3 - 11x^2 + 8x)
= 5x^4 - 6x^3- 11x^2 + 14x

(2x – 1)(x + 7) = 0
2x - 1 = 0
x = 1/2
x + 7 = 0
x = -7
The solution for (2x – 1)(x + 7) = 0 is x = 1/2 , x = -7 .

The solution for Y = 5x – 9 , Y = 2x + 6 is x = 5 , y = 16 .
5x - 9 = 2x + 6
5x - 2x = 6 + 9
3x = 15
x = 15/3
x = 5
y = 5*5 - 9
y = 25 - 9
y = 16
