Subtraction Equations: True or False

**Equations **tell you that two things are **equal.** They always use an equal sign (**=**).

Think of equations as a balance.

Both sides need to be equal so things will be balanced.

It's the same with equations.

Equations are **true** if the value of the left side is equal to the value of the right side.

Here's an example:

5 - 3 = 2

Why is it true?

If we subtract 3 from 5, this is what we get:

5 - 3 = 2

The value of the left side is 2.

The value of the right side is also 2.

2 isequalto 2.

The two sides are equal.

✅ That's why this equation is true.

Equations are **false** if the values of the left and the right sides are **not equal.**

This is an example of a **false **equation:

10 - 6 = 8

Why is it false?

If we subtract 6 from 10, this is what we get:

10 - 6 = 4

The value of the left side is 4.

The value of the right side is 8.

4 isnot equalto 8.

So 10 - 6 is not equal to 8.

10 - 6 ≠ 8

❎ That's why this equation is false.

Equations can have subtraction on either side of the equal sign.

9 - 3 = 8 - 2

Is this equation true?

Let's try to find out by solving each side.

9 - 3 = 6

8 - 2 = 6

Both sides have the same answers.

6 is equal to 6.

6 = 6

✅ This means that this equation is **true**.
