Need help with a system of equations
sweet [91]

Answer:

\boxed{x - y = -2\sqrt{7}}

Given:

x + y = 4 \\  \\  {x}^{2}  +  {y}^{2}  = 22 \\  \\  {x}^{4}  =  {y}^{4}  - 176 \sqrt{7}

Step-by-step explanation:

=  >  {x}^{4}  =  {y}^{4}  - 176 \sqrt{7}  \\  \\  =  >  {x}^{4}  -  {y}^{4}  =  - 176 \sqrt{7}  \\  \\  =  >  {( {x}^{2}) }^{2}  -  { ({y}^{2}) }^{2}  =  - 176 \sqrt{7}  \\  \\  =  > ( {x}^{2}  +  {y}^{2} )( {x}^{2}  -  {y}^{2} ) =  - 176 \sqrt{7}  \\  \\  =  > ( {x}^{2} +  {y}^{2})  (x + y)(x - y) =  - 176 \sqrt{?}  \\  \\  =  > 22 \times 4(x - y) =  - 176 \sqrt{7}  \\  \\  =  > 88(x - y) =  - 176 \sqrt{7}  \\  \\ =  >  x - y =  -  \frac{176 \sqrt{7} }{88}  \\  \\  =  > x - y =  - 2 \sqrt{7}

Identity used:

{x}^{2}  -  {y}^{2} = (x + y)(x - y)
