Solve algebraically the simultaneous equations

x^2 + y^2 =25
y-2x = 5

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

assuming you mean addition: addition and subtraction are reverse operations.
