$\Large\boxed{\textnormal{LESSON: ADD/SUBTRACT EXPANDING EXPRESSIONS }}}$

To simplify this expression, first you have to isolate by the x on one side of the equation.

SOLUTIONS:

You can also used distributive property formula.

$\Large\boxed{\textnormal{DISTRIBUTIVE PROPERTY FORMULA}}$

$\displaystyle A(B+C)=AB+AC$

First, you have to combined like terms. (Group like terms and switch sides.)

$\displaystyle 3x-x-5+928$

Then, you add or subtract elements the numbers from left to right.

$\displaystyle 3X-X=2X$

Rewrite the problem down.

$\displaystyle 2x-5+928$

Solve.

Add and subtract the numbers from left to right.

$\displaystyle -5+928=\boxed{923}$

$\Large\boxed{2x+923}$

So, the final answer is 2x+923.
