{4x+3y=543x+9y=108

Answer 1

Can you send a ss the problem doesn't really make any sense

Answer 2

You can solve it by elmination

Answer 3

How would you know, You can't even tell what the problem is

Answer 4

3 times the first equation minus the second one

Answer 5

If your problem is 4x+3y=54| 3x+9y=108 that's what I'm guessing then..
4 x + 3 y = 54 / · ( - 3 )
3 x + 9 y = 108
- 12 x - 9 y = - 162
3 x + 9 y = 108
- 9 x = - 54 | x = - 54 : ( - 9 ) = 6
4 · 6 + 3 y = 54
24 + 3 y = 54
3 y = 54 - 24
3 y = 30 | y = 30 : 3 = 10
Thus, ( 6, 10 ) Since we know thats what ( x , y ) is ( 6 , 10 )
