# How much greater is the value of 3x + 5 than the value of 3x - 7?

**Solution:**

Linear equations are nothing but yet another subset of "equations".

Any linear calculations requiring more than one variable can be done with the help of linear equations.

The standard form of a linear equation in one variable is of the form ax + b = 0.

It is given that, two linear equations that are 3x + 5 and 3x - 7.

Now we have to find how much greater is the value of 3x + 5 than 3x - 7,

We have to subtract 3x - 7 from 3x + 5.

So, on performing subtraction of 3x - 7 from 3x + 5 we get,

= 3x + 5 - (3x - 7)

= 3x + 5 - 3x + 7

= 12 units

Therefore, the value of 3x + 5 is greater than 3x - 7 by 12 units.

## How much greater is the value of 3x + 5 than the value of 3x - 7?

**Summary:**

The value of 3x + 5 is greater than 3x - 7 by 12 units.
