Answer: 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

Answer:

[tex]x=20[/tex]

Step-by-step explanation:

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

[tex]\frac{1}{2}x + 7 = x-3[/tex]

Subtract 7 from both sides:

[tex]\frac{1}{2}x = x-10[/tex]

Subtract x from both sides:

[tex]-\frac{1}{2}x = -10[/tex]

Multiply both sides by -2:

[tex]x = 20[/tex]

Hope this helped!
