Hey mate

here is your answer

By Elimination method

We can solve this,

let 5x+7y=79 be equation 1

7x+5y=77 be equation 2

Now In order to cancel x variable,

◇ Multiply eqn 1 by 7

◇ Multiply eqn 2 by 5

So you will get

35x+49y=553

35x+25y=385

(-) sign change

____________

24y=168

____________

y=168/24

y=7

y=7 subs in eqn 1

5x+49=79

5x=30

x=6

Solution

x=6

y=7

same way you can cancel y variable too you get the same answer

hope this helps you :)

keep smiling
