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

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

The ratio of roots of the equation mx² + nx + n = 0 is α/ β = a/b, then find the value of `sqrt(a/b)+sqrt(b/a)+sqrt(n/m)`

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

4x + 6y = 16 and 8x + 12y = 32

If (5√P - 7√Q) = 5, [1.5P = 4Q-(R/3)+9] and (√P/√Q) = 1.6, then find out the value of ‘R’.

The ratio of roots of an equation

ax²+bx+b = 0 is p : q

Then find, √p/√q + √q/√p + √p/√q ?

I. p² – 5p + 6 = 0                  

II. 36q² = 81

I. p² - 365 = 364

II. q - √ 529 = √ 169
