Answer: 3:5
Step-by-step explanation:
33x-54y=6x+6y-3x-10y
33x-54y=3x-4y
30x=50y
3x=5y
Answer:
The essence of Mathematics lies in its freedom
Answer:
y = -
Step-by-step explanation:
Substitute x = - 3 into the expression
2x - 7y = 30
2(- 3) - 7y = 30
- 6 - 7y = 30 ( add 6 to both sides )
- 7y = 36 ( divide both sides by - 7 )
y = = -
In your head....9-15= -6...then (in your head) you would divide both sides by a negative to get x alone. So x=6.. (In your head).
2. Is a Function and oof kinda forgot the rest sorry
