Question

What are the ordered pairs for y=1/3x+4 , y=2x-1?

Answer 1

`(x,y)=(3,5)`

Explanation:

If `color(white)("XXX")y=1/3x+4`
and `color(white)("XX")y=2x-1`
then
`color(white)("XXX")2x-1=1/3x+4`

`color(white)("XXX")5/3x=5`

`color(white)("XXX")x=1`
`color(white)("XXXXXXX")`and substituting this `rarr y=1/3x+4`

`color(white)("XXXXXXXXXXXXXXXXXXXX")` gives `y=5`
