Solve algebraically the simultaneous equations<br><br> X^2 + Y^2 =25<br> Y-2X = 5
Georgia [21]

Answer:

Therefore the solutions are

x=0\\and\\ y =5\\\\Or\\\\x=-4\\and\\y=-3

Step-by-step explanation:

Given:

x^{2} + y^{2} =25 .........( 1 )

y-2x = 5\\y=2x+5     ................( 2 )

To Find:

x = ?

y = ?

Solution:

Substituting ' y ' in Equation  1 we get

x^{2}+(2x+5)^{2} =25

Using identity (A+B)²=A²+2AB+B² we get

x^{2}+4x^{2}+20x+25=25\\\\5x^{2}+20x=0\\5x(x+4)=0\\5x=0\ or\ x+4=0\\x=0\ or\ x= -4

Now Substitute x =0 in equation 2 we get

y=2\times 0+5=5

Or

Now Substitute x =-4 in equation 2 we get

y=2\times -4+5=-3

Therefore the solutions are

x=0\\and\\ y =5\\\\Or\\\\x=-4\\and\\y=-3
