A system of equations is shown below:

Question

x + y = 3
2x − y = 6

The x-coordinate of the solution to this system of equations is _____.
I'm thinking it could be X=3

Answer 1

Your thinking could be right, but what made you think it is, and why ?

Answer 2

A system of equations is shown below:

6x − 5y = 5
3x + 5y = 4

The x−coordinate of the solution to this system of equations is _____.

Answer 3

To solve this equations, you have to use the elimination or addition method. You have to eliminate the y's since you want to find the x-coordinate. Then solve for the rest of the equation...
