Your thinking could be right, but what made you think it is, and why ?
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 _____.
6x − 5y = 5
3x + 5y = 4
The x−coordinate of the solution to this system of equations is _____.
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...
