Answer:

The solution of the given equations

x =4 , y = 1

Step-by-step explanation:

<u>Explanation</u>:-

<u>Step(l</u>):-

Given the system of equations -5x+13y = -7 ..(l)

                                                     5x+4y=24 ..(ll)

<u>Step(ll)</u>

Adding (l) and (ll) equations and cancelling '5x' terms we get

         13y+4y = -7 +24

               17y = 17

dividing '17' on both sides, we get

                y=1

<u>Step(lll):-</u>

Substitute y=1 in equation (l) , we get

-5x+13y = -7

-5x + 13(1) = -7

subtracting '13' on both sides, we get

-5x +13 -13= -7 -13

-5x = -20

Dividing '-5' on  both sides, we get

x = \frac{-20}{-5}

x = 4

<u>Conclusion</u>:-

The solution of the given equations

x =4 , y = 1

Can i simplify 21/8
kakasveta [241]
When you're looking to simplfy a number, the best thing to do is to list all of the factors of that number; 21- 1,3,7 8- 1,2,4,8 The only common factor between these is one, and this is what they're currently in, therefore, it cannot be simplified. Hope this helps :)
