Answer:

(1,3)

Step-by-step explanation:

Since we already have the variable to it self, we can substitute y=4x-1 into 2x+y=5.

So it would be 2x+(4x-1)=5

Remove the parentheses

Combine like terms

Move the constant to the right

Divide 6 on both sides to get the variable by it self.

x=1

Then we substitute x=1 into y=4x-1, so..

y=4(1)-1

y=4-1

y=3

So the answer would be (1,3).

Hoped it helped!
