Answer:
n < 3
Step-by-step explanation:
6n + 10 < 4n + 16
( Minus 4n from both sides to isolate + 16 )
2n + 10 < 16
( Minus 10 from both sides to isolate 2n )
2n < 6
( Divide both sides by 2 to isolate n )
n < 3

Answer:
Step-by-step explanation:
2x + 5y = 6 --------( 1 )
5x - 2y = 9 --------( 2 )
_____________
( 1 ) x 5 => 10x + 25y = 30 -----------( 3 )
( 2 ) x 2 => 10x - 4y = 18 ----------- ( 4 )
______________
( 3 ) - ( 4 ) => 0 + 29y = 12
Substitute y in ( 1 ) =>
