What is the solution to the following system of equations?

4x + 2y = 6
x − y = 3

x = 2, y = -1

Step-by-step explanation:

4x + 2y = 6   eq 1

x − y = 3   eq 2

Using elimation method:

eq 2 x 2

2 (x − y)= 2(3 )

2x - 2y = 6 eq 3

eq 1 + eq 3

4x + 2y + 2x - 2y = 6 + 6

6x = 12

x = 2  (sub this back into eq 2)

x − y = 3

2 − y = 3

-y = 3 - 2

-y = 1

y = -1

what grade level is this? need to know so i can look in my old textbooks!
