sorry I have that much qualifications to work on this question and hoping this much will make bit easy for you to solve it further
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
To be able to compare 2 fraciton we have to make common denominator and then we can just compare numerators.
Now we can compare numerator from the first (9) and from the second fraction (8)
9>8, so the bigger is 9/10
