Answer:
Step-by-step explanation:
Given the simultaneous equation
3x+4y=15. Equation 1
3x-y=30. Equation 2
Using elimination method
Sutract equation 2 from 1
Then, will have
3x-3x+4y--y=15-50. -×-=+
4y+y=-15
5y=-15
Divide Both sides by 5
y=-15/5
y=-3
From equation 2
3x-y=30
3x--3=30
3x+3=30
3x=30-3
3x=27
Divide both side by 3
x=27/3
x=9
Then, x=9 and y=-3
Is there a math question and can you show it please
This would be the correct answer
Answer: 0
Step-by-step explanation:
100/4 = 25 because 25x4=100 then 25 is rounded down to 0 because it’s below 50. If it was 60 we would round it up to 100
