Question

Solve the linear equation by elimination method 0.8x+0.5y=0.9;0.6x+0.7y=0.3y

Answer 1

`x = (24)/(13) and \: y = ( - 25)/(13)`

Explanation:

I believe your equation 2 is meant to be

`0.6x +0 .7y = 0.3`

If so then change both equations 1 and 2 to fraction form

`(8)/(10) x + (5)/(10) y = (9)/(10)....equation1 \\ (6)/(10) x + (7)/(10) y = (3)/(10)....equation2`

Finding the lcm and then solve therefore

`x = (24)/(13) and \: y = ( - 25)/(13)`
