For given pair of equations, how many solutions are possible?

3x + 4y = 15 and 6x + 8y = 10

I. 8/(√x) + 6/(√x) = √x

II. y ³- (14)^7/2 /(√y) = 0

Solve: 2x + 3y = 19 and x − y = 2, Find x and y

If α and β are roots of the equation x² - 9x + 20 = 0, then find α² + β².

 If the point of intersection of the lines 2x + y = 11 and x - y = 1 is P(a, b), then the value of a + 2b is:

The lines x + y = 9 and x - y = 3 intersect at point P. Find the coordinates of P.

If x - √3 y = 8 Find the slope in angle?

Solve: (x/3) + (x/5) = 16

If x and y are roots of x² − 7x + 12 = 0, then find (1/x + 1/y).
