help i am stuck :
-8 - 5y = 12 - 9y
i got:
-8-12 -5y = 12-12 - 9y
-20 - 5y = 9y
-20 +20 - 5y - 9y
im so stuck idont understand this one can you please help me
-8 - 5y = 12 - 9y
-5y + 9y = 12 + 8
4y = 20
y = 5
thanks and to check
-8 -5(5) = 12 -9 (5)
-8-25 = 12 - 45
-33 = -33 true
thanks
got time for 1 more -- please :)
8 - 3 (p-4) = 2p
i got:
8 - 3p - 12 = 2p
now im stuck
You're welcome.
8 - 3 (p-4) = 2p
8 - 3p + 12 = 2p
20 = 2p + 3p
20 = 5p
4 = p
You seem to be forgetting that multiplying two negative numbers produces a positive number. Watch your signs!
wait i think i got it:
8 - 3p -12 = 2p
12 + 8 = 20
20 - 3p = 2p
+3p = +3p
20 = 5p
-------------
5 5
4 = p is that right
Yay! You've got it!
thank you i really glad you cheked my work i feel better now. its clicking
thanks and good night
Sure, I'd be happy to help you with this equation.
The equation you provided is: -8 - 5y = 12 - 9y.
To solve for y, we need to simplify the equation by combining like terms and isolating the variable y on one side of the equation.
Let's simplify the equation step by step:
First, we can simplify the left side by adding -8 and -5y:
-8 - 5y = -8 - 5y
Next, we can simplify the right side by adding 12 and -9y:
-8 - 5y = 12 - 9y
Now, let's gather all the y terms on one side by adding 5y to both sides:
-8 - 5y + 5y = 12 - 9y + 5y
-8 = 12 - 4y
Next, let's simplify the equation further by subtracting 12 from both sides:
-8 - 12 = 12 - 12 - 4y
-20 = -4y
Finally, let's isolate the y term by dividing both sides of the equation by -4:
(-20) / (-4) = (-4y) / (-4)
5 = y
So, the solution to the equation is y = 5.
I hope this explanation helps you understand how to solve this type of equation. If you have any further questions, feel free to ask!
