X-y equals 8 and 2x plus y equals 7?
x=5 y=-3
Solve using elimination x plus y equals 8 and x minus y equals 6?
X + y = 8 x - y = 6 add equations to eliminate y 2x = 14 x = 7 substitute 7 + y = 8 y = 1
What is the answer for the ordered pair form x plus seven y equals 7 two x plus y equals 8 using substitution?
If you mean: x+7y = 7 and 2x+y = 8 Then by substitution: x = 49/13 and y = 6/13
The addition method for x plus y equals 8 and -x plus 2y equals 7?
Add the two equations: x + y - x + 2y = 8 + 7 ie 3y = 15 so y = 5 making x = 3.
