You can verify section formula by graphical method if you cannot solve it using algebra.
Add the equations: 4a + 4a - 5b + 5b = 7 + 17 ie 8a = 24 a = 3, so b = 1
a2+30a+56=0 , solve for a Using the quadratic formula, you will find that: a=-2 , a=-28
Solve the problem using the + sign for the variable. Then solve the problem using the - sign for the variable. Report your answer as the answer that you got using + or the answer that you got using -.
the answer
(2,-2)
Yes and it works out that x = 3 and y = 4
x=1, y=1
4
By elimination: x = 3 and y = 0

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.
The graphical method is a method used to solve algebraical problems by using graphs.
