How do you solve 3x+5y=43 & 5x+7y=65

please help me i dont know what to do

x=6 and y=5
And idk how I found out lol

3x + 5y = 43, multiply by - 5/3
5x + 7y = 65

- 5x - (25/3)y = - 215/3
5x + 7y = 65
-----------------------------------
- (4/3)y = - 20/3

y = 5

3x + 5y = 43
5x + 7y = 65, multiply by - 5/7

3x + 5y = 43
-(25/7)x - 5y = - 325/7
--------------------------------
- (4/7)x = - 24/7

x = 6

(6, 5), answer!
