El tema es de magnitudes proporcionales "x + 2" varia en forma directamente proporcional a "y - 2". Si x=10" cuando
"y = 6"; hallar "x" cuando "y" es igual a 10

i got 86 for this

hope this !

if you need an explanation just ask

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
