To solve Linear Equations by cross-multiplication method, we bring all the terms to the left hand side in the first step. For example, if we have equations and , we write them as:

and

In general we can say that equations have to be in form:

Let's suppose that we want to solve equations:

To solve the above equations by cross-multiplication method, we do following:

At this point we can make two equations. One equation can be used to solve for and the other one can be used to solve for .

Two equations are:

and

Now let's take an example, we have two equations to solve:

In the first step, we bring terms present on the right hand side to the left hand side.

**(1)**

And, **(2)**

Using **cross multiplication** method, we write

and

and **(This is the solution)**

Let's do one more example for good understanding.

I have following equations to solve:

In the first step, we bring terms present on the right side to the left side.

**(1)**

And, **(2)**

Using cross-multiplication method, we can write

and

and

Therefore, and **(This is the solution)**
