Solve 1/2x + 7 = x - 3

x=20

Step-by-step explanation:

1/2x + 7  =x -3            add 3 to both sides

          +3      +3

1/2x + 10 = x          Subtract 1/2x from both sides

-1/2x          -1/2x

        10 = 1/2x

  x = 20

Step-by-step explanation:

We can solve for x by simplifying the equation until we have x isolated on one side.

Subtract 7 from both sides:

Subtract x from both sides:

Multiply both sides by -2:

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)
