How can you get coefficients that are equal for x?
12x + 6y= 13
4x+6y= 12

Here now the Coefficient of x is same that is 12.

Step-by-step explanation:

Given:

....Equation ( 1 )

....Equation ( 2 )

To Solve:

To make coefficients that are equal for x ?

Solution:

....Equation ( 1 )

We will make Equation ( 2 ) coefficient same by multiplying throughout by 3 we get

Applying Distributive Property A(B+C)=AB+AC we get

........as required

Here now the Coefficient of x is same that is 12.

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !
