# How do you solve #7x - 9 = -10 + 4x#?

##### 3 Answers

#### Explanation:

Rearrange the equation so all x-terms are on one side and constants are on the other, then solve for x. This gives you

#### Explanation:

First, we should rearrange the constants so they are all on one side. I prefer having constants on the Right Hand Side (RHS) as opposed to the Left Hand Side (LHS).

We can rearrange by adding/subtracting values from both sides of the equation.

For this problem, we will first add 9 to both sides of the equation. This will eliminate the -9 from the LHS, and effectively move its value to the RHS:

Now, we'll move the

Finally, divide through by any coefficients that

#### Explanation:

You can do operations to one side of an equation, including but not limited to with variables, if you also do it to the other side. Through this you can eliminate parts of both sides to solve the equation to get

Line 1 to 2: taking away

Line 2 to 3: adding

Line 3 to 4: dividing both sides by
