Answer:
x=0,y=-3
Step-by-step explanation:
3x-5y=15 - equation(1)
x-4y=12 => x=12+4y -equation (2)
Replace equation (2) in equation (1)
3(12+4y)-5y=15
36+12y-5y=15
7y=15-36
7y= -21
y = -21/7
y=-3
If y=-3,then replace in equation (1) ; 3x -5(-3)=15
3x+15=15
3x=0
x=0
Answer:
x>4
x>4
x>4
Step-by-step explanation:
x+6>10
x+6-6>10-6
x>4
x+4,446>4,450
x+4,446-4,446>4,450-4,446
x>4
Answer:
Step-by-step explanation:
