Question

9x-2y-1=0,3x+2y-8=0,solve for x by cross multipication​

Answer 1

Step-by-step explanation:

9x - 2y -1 = 0

3x +2y -8 = 0

x / (-2)(-8) - (2)(-1) = y / (-1)(3) - (-8)(9) = 1 / (9)(2) - (3)(-2)

x/(16 +2) = y/(-3+72) = 1/(18+6)

x/18 = y/69 = 1/ (24)

x/18 = 1/24

24x = 18

x = 18/24 = 2/3 (or) 0.67
