The roots of the quadratic equation $ax^2+bx+c=0$ are

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$ .

Here the given quadratic equation is $5x^2-13x+7=0$ . Here $a=5,b=-13,c=7$ .

The roots are

$x=\frac{13 \pm \sqrt{13^2-4*5*7}}{2*5} \\ x=\frac{13 \pm \sqrt{29}}{10}$

B) 3x + 2y = 36 Adding both equations eliminates "y"

8x = 48

x = 6 Putting x=6 into equation B we get

3*6 + 2y = 36

2y = 18

y = 9
