Answer:


\Huge \boxed{X=7}

Explanation:

To solve this problem, first you have to isolate it on one side of the equation. So remember to solve this problem, addition property of equality is adding from both sides of an equation to the same number doesn't change the equation.

First, add 3 from both sides.


\displaystyle x-3+3=4+3

Solve.


\displaystyle 4+3=7

As a result, the correct answer is x=7.

Hope this helps!

Have a wonderful blessing day! :)

Good luck! :)

x - 3 = 4

We need to isolate x. To do this add 3 to both sides (what you do on one side you must do to the other). Since 3 is being subtracted from x, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.

x - 3 + 3 = 4 + 3

x + 0 = 7

x = 7

Hope this helped!
