Using the multiplication property, we have the following equivalent system of linear equations:

  • 4/9x + 4/3y = 20/12  
  • 2/3x - 4/3y = 5/3

<h3>What is an Equivalent System of Linear Equations?</h3>
  • Systems that are equivalent will have the same solution.
  • Creating equivalent system helps us to find the variables in a system of equations.

Given:

1/3x + y = 5/4 ---> Equation 1

2/3x - 4/3y = 5/3 ---> Equation 2

To create an equivalent system, multiply equation 1 by 4/3, and multiply equation 2 by 1.

Thus, using the multiplication property, we have the following equivalent system of linear equations:

  • 4/9x + 4/3y = 20/12  
  • 2/3x - 4/3y = 5/3

a store sells for 25% off the regular price the regular price of a beach towel is 24.50 which expression represents the scale pr
UNO [17]

24.5 \times 1.25 = 30.625
Since you're adding on to the regular price, you can say it is 125% of the price. Or you can use the regular equation:
(24.5 \times .25) + 24.5 = 30.625
Since you're only finding 25% of 24.5, you have to add on 24.5 because you're paying for the beach towel and applying the sales tax.

Now, since cents are to the hundredths place, you have to round.
The final price would be $30.63

What is 2/3x+4=4/5x-2
Anuta_ua [19.1K]

Hey there!

Apply  fraction cross multiply: if a/b = c/d , then  a *d = b*c

2 ( 5x - 2 ) = ( 2x + 4 ) * 4

expand : 2 (5x-2 )  => 2*5x - 2*2 => 10x - 4

expand : ( 2x +4 ) * 4 =>  2x * 4 + 4*4 => 8x + 16

10x - 4 = 8x+16

add 4 to both sides:

10x-4+4 = 8x+16+4

simplify :

10x  = 8x + 20

subtract 8x from both sides:

10x -8x = 8x+20-8x

simplify:

2x = 20

Therefore:

x = 20 / 2

x = 10


Hope that helps!
