4( -x + 4 ) = 12 need a bit of checking my work

Remember to follow PEMDAS. Remember that the goal is to isolate the x.

First, distribute 4 to all terms within the parenthesis. Remember the signs.

4(-x + 4) = -4x + 16

-4x + 16 = 12

Next, isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 16 from both sides.

-4x + 16 (-16) = 12 (-16)

-4x = 12 - 16

-4x = -4

Next, isolate the x. Divide -4 from both sides

(-4x)/-4 = (-4)/-4

x = -4/-4

x = 1

1 is your answer for x.

hope this helps

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)
