Answer:
Explanation:
Method to solve system by elimination :
Let me give an example :
a(x) + b(y) = c
d(x) + e(y) = f
multiply equation 1 by d and 2 by a
ad(x) + bd(y) = cd
ad(x) + ae(y) = a(f)
Now subtract or add as given in the situation .
y(bd - ae) = cd - a(f)
y = (cd - a(f))/(bd - ae)
Now put the value of y in 1 or 2 and get the value of x
