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
