Answer:
Therefore the solutions are
Step-by-step explanation:
Given:
.........( 1 )
................( 2 )
To Find:
x = ?
y = ?
Solution:
Substituting ' y ' in Equation 1 we get
Using identity (A+B)²=A²+2AB+B² we get
Now Substitute x =0 in equation 2 we get
Or
Now Substitute x =-4 in equation 2 we get
Therefore the solutions are
1*160
2*80
4*40
5*32
8*20
10*16 ..... Etc...
