What is 6x3+2-1=?
Brainliest

19

Step-by-step explanation:

6x3=18+2=20-1=19

(6x)3 + 2-1=

18x+1

Multiply by 3 first next add 18x+2 finally subtract by 1 equal to 18x+1

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)
