Question 259897: solution for:
x+2y=7
x+6y=1 (ordered pairs!)

You can put this solution on YOUR website!
x + 2y = 7
x + 6y = 1
------------ subtraction eliminates x
0 - 4y = 6
-4y = 6
y = 6%2F%28-4%29
y = -1.5
:
Find x using x + 6y = 1
x + 6(-1.5) = 1
x - 9 = 1
x = 1 + 9
x = 10
:
The ordered pair 10, -1.5
:
:
Check solution in the 1st equation
x + 2y = 7
10 + 2(-1.5) = 7
10 - 3 = 7, confirms our solution
