Question

A system of equations is shown below: 3x − y = 2 x + y = 6 The x-coordinate of the solution to this system of equations is _____.

Answer 1

3x - y = 2x + y = 6

you move y and x

3x - 2x = y + y = 6

now you you results you solution
x = 2y = 6

Answer 2

3x - y = 2x + y = 6
3x - 2x = y + y = 6
x = 2y = 6
