# Question #91885

##### 3 Answers

I am assuming the problem is

The first step would be to simply

Then I would change the mixed number to a fraction.

To clear the fractions in this equation you will need to find the least common multiple for each of the fractions (in this cast 30) and multiply each term by it.

I would multiply each side of the equation by 30.

Then I would use the distributive property and multiply each term and then simplify the expressions.

and

Assuming that the two equations in the question are

First step is to multiply each equation with the LCM of denominators of all the terms in that equation so as to get rid of the fractions.

Next step is to bring all unknowns to the LHS and constants on the RHS

For (1) we see that LCM of the denominators of its three terms,

Similarly for equation (2)

Solve (3) and (4) for the unknown

To eliminate

Inserting this value in (3)

#### Explanation:

Luckily with equations, you can change the form into into one which suits you.

Do anything you like as long as you do the same thing to both sides. Multiply by the LCM to cancel the denominators

Now you have two equations which are both in a better form and we can solve them simultaneously:

Substitute
