Question

How do you solve the system of equations: 2x - y = 36 ; 3x - 0.5 = 26?

Answer 1

The solutions are
`color(blue)(x=8.33, y=-19.34`

Explanation:

`2x - y = 36`

`3x - 0.5 = 26`
`3x = 26+0.5`
`3x=26.5`
`x=26.5/3`

`x=color(blue)(8.33`

Finding `y` from the first equation
`2x - y = 36`

`2x - 36=y`

`y= 2*(8.33) -36`
`y=16.6-36`
`color(blue)(y=-19.34`
