3х + 1 = -11
What is the answer?

-4

Step-by-step explanation:

3x+1=-11

    -1   -1  

3x=-12

/3   /3

 x = -4

x=-4  

Step-by-step explanation:

3x+1=-11

subtract one from both sides

3x+1= -11

    -1    -1

3x=-12

divide by 3 on both sides

3x/3     -12/3

x= -4   

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)
