Re: For instance if I have a problem of 4x+1-x=2x-13+5....
Hi,
This calculator does not have a Solve function or a solver. However this example of yours is very simple that you can do it by hand. If you do not mind I will show you how to solve it. Not everything needs a calculator.
You want to solve for x. OK
- Start by gathering similar terms 4x-x =3x; -13+5 =-8
- Rewrite your equation as 3x+1=2x-8
- Make the +1 change side while changing its sign
- 4x+1 -1 = 2x-8 -1 or 4x=2x-9
- Make +2x on the Right hand side go to the left hand side, changing its sign in the process 4x-2x=-9 or 2x=-9
- Divide both members by 2. This gives
- x=-9/2 or -4.5 if a decimal result is required.
Hope it helps.
