How to solve Equation with the variable on both sides 1 - 2x = -x - 3

Answer 1

The solution is $x=4$

Step-by-step explanation:

The starting equation is

$1-2x=-x-3$

The first step to do is to bring all the terms in the variable on the same side. To do that, let's start by adding $+2x$ on both sides:

$1-2x+2x = -x-3+2x$

and we get

$1=-3+x$

Now we add +3 on both sides:

$1+3=-3+x+3$

And we get

$4=x$

So the solution is $x=4$.
