Ответ:
The solution set would be (2, -1)
Step-by-step explanation:
To find the solution set, use the elimination method. You can do this my multiplying the whole first equation by 2 and then adding the two equations together.
6x + 4y = 8
2x - 4y = 8
8x = 16
x = 2
Now that we have the value of x, solve for y using either equation.
2x - 4y = 8
2(2) - 4y = 8
4 - 4y = 8
-4y = 4
y = -1
