Question

6x-12y=1 and 8x-9y=18 find out x and y ?

Answer 1

x=8.01. y=4.09. by simple mathod

Answer 2

You have to solve this simultaneously:
8(6x-12y=1)
6(8x-9y=18)

48x-96y=8
48x-54y=108

48x-48x=0
-96y+54y=-42y
8-108=-100

-42y=-100
y=2.38

Substituting y in the initial equation
6x-12y=1
6x-12(2.38)=1
6x-28.56=1
6x=29.56
x=4.93
