Get the equation simplified. Subtract 4 by each side.
20-4= 16
and the square root of 16, is 4.
Plug it in to check.
(4)^2+4=20
16+4=20
20=20
Ultimately your final answer is X=4
<span>Multiply equation(2) with 4 so that coefficient of become same in both the equations(You can make coefficient of y same and can follow the following procedure.)
</span><span>* Subtract (3) from (1)
* </span>Divide both sides by -19
*Subtract 21 from both sides.
*Divide both sides by 4
so the solution is x= 3 and y= -7
