3x + 3 = 3y < -- make this 3x - 3y = -3
2x - 6y = 2
multiply by 2 on the first equation
6x - 6y = -6
2x - 6y = 2
subtract them
4x = -8
x = -2
substitute x = -2 into any of the equation
2x - 6y = 2
2(-2) - 6y = 2
-4 - 6y = 2
-6y = 6
y = -1
So the answer is
(-2 , -1)
Answer:
= x² + 7x + 70
Step-by-step explanation:
-7x - 60 = x² + 10
= -x² - 7x - 60 - 10
= -x² - 7x - 70
= x² + 7x + 70
Answer:
BC = 50
Step-by-step explanation:
I believe what I'm doing is correct but to be completely honest with you, I haven't done this in a while lol
Okay so...
You would do
1. 6y-16 = 4y+6
You would subtract 4 from 6...
2. 2y-16 = 6
You would then add 16 to 6...
3. 2y = 22
Then, divide 2 from 22...
4. y = 11
Substitute into BC...
5. 6 (11) - 16 = 66 - 16 = 50
Then, you get your final answer...
6. BC = 50
I hope it's right. Good luck ^^
