Answer:
Step-by-step explanation:
First: multiply both sides by 4. 4 times c is 4c and the other sides cancels out as you are doing the inverse operation of division
Then, you have 
Subtract both sides by a squared
DO NOT TAKE THE SQUARE ROOT! This is because it is a squared plus 3b so you have to do the inverse of addition
From that you get 
Finally, divide both sides by 3.
You get
9/16.
There is no common factor to 9 and 16.
No number can go into 9 and at the same time go into 16.
So in simplest form it is still = 9/16
3x + 3 = -2x + 2 - 4
3x + 3 = -2x - 2
Add 2 to each side
3x + 5 = -2x
Subtract -3x from both sides
5 = -5x
Divide each side by 5
1 = -x
Since you can leave x negative you reverse it with 1 and your answer will be >>> x = -1
Step-by-step explanation:
-(3x+y=32)
3x-2y=17
-3x-y=-32
3x-2y=17
-3y=-15
y=5
3x+(5)=32
-5. -5
3x=27
x=9
Answer:
x=9
y=5
Answer:
It didn't
Step-by-step explanation:
This is because the coupon adds them for free, this means that one week she got 15 instead of 12. This had no effect on the cost of her perscription because it was free.
