When a firm operates with excess

If in two linear equations ax + by = c and dx + ey = f and a/d = b/e = c/f  then, which of the following is true about the two equations?

The equations 6x + my + 18 = 0 and 9x + 21y + 27 = 0 have a unique solution. Which of the following statements is definitely true?

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

I. p² - 365 = 364

II. q - √ 529 = √ 169

A line passes through the points (2, 3) and (5, −3). Find its equation.

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

2x + 3y = 10 and 4x + 5y = 18

For which value of m, there is no solution to the equation -

a – b = 5

ma – 4b = 1

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

I. p² – 5p + 6 = 0                  

II. 36q² = 81
