The sum of a number and three times its reciprocal is 52/7. Find both possible answers

x+3*1/x=52/7

7x^2/7x+21/7x=52x/7x

7x^2-52x+21=0

I solve this with the quadratic formula

Solution of ax^2+bx+c=0, a≠0 are :

x1=  and x2=

so a=7, b=-52,c=21

x1== (52+46)/14=98/14=7

x2=(52-46)/14=6/14=3/7

Step-by-step explanation:

i dont get it. where are the "descriptions"?

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
