there were 6 inche of snow on the street. After a storm, the snow increased by 2/3 of the original amount. After a sunny day, 2/3 of the snow melted. How many inches of snow is there now

6 inches.

Step-by-step explanation:

plus 2/3 and minus 2/3

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
