7x=4x+27

1 answer

To solve for x, you want to move all terms containing x to one side of the equation and all other terms to the other side.

Starting with the equation:

7x = 4x + 27

Subtracting 4x from both sides:

7x - 4x = 4x - 4x + 27

This simplifies to:

3x = 27

Finally, divide both sides of the equation by 3:

3x/3 = 27/3

This gives:

x = 9

Therefore, the solution is x = 9.
