Answer:
X = (-2)
Y = (-5)
- 7x + 5y= (-11) -------(1)
-4x + 3y,= (-7) ----------(2)
Solving by using elimination method
Multiplying eq 1 with 3 and eq 2 with 5
3( -7x + 5y) = 3(-11)
5(- 4x + 3y) = 5(-7)
-21x + 15y = (-33)
-20x + 15y,= (-35)
Subtracting both the eq.
-x = 2
x = (-2)
Putting this value in eq. 1
- 7x + 5y= (-11)
-7(-2)+ 5y= (-11)
14 + 5y = (-11)
5y = (-11) - 14
5y= (-25)
y = (-5)
