Question

A system of equations is shown below: x + y = 3 2x − y = 6 The x-coordinate of the solution to this system of equations is _____. Numerical Answers Expected! Answer for Blank 1:

Answer 1

3

Explanation:

First equation :

x = 3 - y

Substitute into the second equation.

2(3 - y) - y = 6

6 - 2y - y = 6

6 - 3y = 6

-3y = 0

y = 0

Substitute back into the first equation.

x + 0 = 3

x = 3

The x coordinate is 3.
