Question 148123: I am trying to solve the following system of linear equation.
x/4 - y/11 = -9/44
x/6 - y/13 = -1/26
Now i am familiar with the methods of solving these types of problems, such as addition method and substitution method, but when it comes to fractions, I'm lost.
When you solve, would it be possible to explain each step.
Thanks for all your help.

Start with the first equation.

Multiply both sides by the LCD to clear any fractions.

Distribute and multiply.

------------------------------------------------

Move onto the second equation.

Multiply both sides by the LCD to clear any fractions.

Distribute and multiply.

So now we have the system

Let's solve this system by use of elimination.

Multiply the both sides of the first equation by 6.

Distribute and multiply.

Multiply the both sides of the second equation by -4.

Distribute and multiply.

So we have the new system of equations:

Now add the equations together. You can do this by simply adding the two left sides and the two right sides separately like this:

Group like terms.

Combine like terms. Notice how the y terms cancel out.

Simplify.

Divide both sides by to isolate .

Reduce.

------------------------------------------------------------------

Now go back to the first equation.

Plug in .

Multiply.

Add to both sides.

Combine like terms on the right side.

Divide both sides by to isolate .

Reduce.

So our answer is and .

Which form the ordered pair

.

This means that the system is consistent and independent.

Notice when we graph the equations, we see that they intersect at

. So this visually verifies our answer.
