X + y = 8
x - y = 6
add equations to eliminate y
2x = 14
x = 7
substitute
7 + y = 8
y = 1
(2,-2)
By elimination: x = 3 and y = 0
Solve using the quadratic formula
You cannot solve one linear equation in two variables. You need two equations that are independent.
Yes and it works out that x = 3 and y = 4

It can be solved by using the quadratic equation formula.
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.
-2
No. Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
i think you should add them
