Question

Y=x-4
4x+y=26
Solve with substitution

Answer 1

(6,2)

Explanation:

Since
`y=x-4`, we can substitute this into the second equation so that there is only one variable that we can solve for.

`4x+(x-4)=26`

`5x-4=26`

`5x=30`

`x=6`

Now we can plug this back into the first equation.

`y=(6-4)`

`y=2`
