Question

Solve the pair of simultaneous equations
x = 4 - y
x = y + 2

Answer 1

The solution to this system of linear equations is (3, 1).

Explanation:

Here we have two equations for x. We can eliminate x by setting these two equations equal to one another, obtaining 4 - y = y + 2, or 2 = 2y

Then y must be 1. Substituting this into the first equation, we get x = 4 - 1 = 3.

The solution to this system of linear equations is (3, 1).

Answer 2

(3,1)

x=3; y=1
