Can you please add more information please? I don't know what numbers to use, so please include more information?

2.5 cm ≈ 1 in

You can use a ruler too. But the exact measurement is:

2.4 cm = 1 in

So, you're on a PC? But thank you. I will do it later.

It still won't work. I will go on my PC and do it there.

But thanks.

Yes. Depends on the expression you are using. 

No.

$$9+10=19$$

$$2*2=4$$

yes it can.

$$\frac{14}{2x}$$  can be simplified into  $$7x$$ . just divide the 14 by 2, and the 2 by 2.

ok. ask someone that has a computer. it works better.

Ok.

Switch the problem so it could look like this:

$$19-14=b$$

Now, subtract.

$$19-14=5$$

Now, change the problem back to its original form:

$$14-5=19$$

Because the postive 5 making the statement false, put the negative symbol behing the 5.

$$-{\mathtt{5}}$$

Now, put the equation with -5.

$$14-(-5)=19$$

So,  $$\boxed{b=-5}$$ .

There is another way to solve this. if you are confused, just ask, and I will give an easier explanation.
