# How do you solve  4x - 9 = 7x + 12 ?

Jan 7, 2017

You move the terms around to get the answer.

#### Explanation:

Let's take another look at the problem:

$4 x - 9 = 7 x + 12$

Using the Subtraction Property of Equality, we can subtract $4 x$ from both sides to turn the equation to this:

$- 9 = 3 x + 12$

And then we can use the Subtraction Property of Equality again by subtracting 12 from both sides:

$3 x = - 21$

Then, we can use the Division Property of Equality to divide 3 from both sides, leaving the answer:

$x = - 7$
