How to solve this question ineed solution too

The answer is: -3y/-y+4

Y=2+x  3/x+2+ 4/2+x)x=1= 3(x+2)/x(x+2)+4x/x(x+2)=1
y=2+x 3(x+2)+4x=x(x+2)=3x+6+4x= x^2+2x 
0=x^2+2x-3x-6x-4x=0
x^2-5x-6=0
a   b   c
x12= formula -b+- radical b^2-4ac divided by 2a=5+-radical 25+24 divided by 2
5+-7 divided by 2 = 6,-1 answer for x and y
