Question

Cross Multiply these two equations:

5x - 2y - 2 = 0
2x + 3y - 16 = 0

Also tell me that how you did it?

Have a Good Day ahead!☺

Answer 1

Given Equation is 5x - 2y - 2 = 0   ------- (1)

a1 = 5, b1 = -2, c1 = -2.

Given Equation is 2x + 3y - 16 = 0  ------- (2)

a2 = 2, b2 = 3, c2 = -16.


Now,

$x = \frac{b1c2 - b2c1}{a1b2 - a2b1}$

          = $\frac{(-2)(-16) - (3)(-2)}{(5)(3) - (2)(-2) }$

          $= \frac{32 + 6}{15 + 4}$

          $= \frac{38}{19}$

          $= 2$


Now,

$y = \frac{c1a2 - c2a1}{a1b2 - a2b1}$

           $= \frac{(-2)(2) - (-16)(5)}{(5)(3) - (2)(-2)}$

           $= \frac{-4 + 80}{15 + 4}$

           $= \frac{76}{19}$

           $= 4$



Therefore x = 2, y = 4.


Hope this helps!
