The answer is x=-5

Here’s the steps:

3(3x+5)=2(2x-5)
Distribute
9x+15=4x-10
Subtract 4x from each side
5x+15=-10
Subtract 15 from each side
5x=-25
Divide each side by 5
x=-5

Answer:

-5

Step-by-step explanation:

3(3x + 5) = 2(2x - 5)

9x + 15 = 4x - 10

9x - 4x = -15 - 10

5x = - 25

x = -5

Nicki has 30 pencils. for every green pencil, she has 5 purple pencils. how many pencils of of each color could she have
Hatshy [7]

Answer:


Step-by-step explanation:


(1) P = 5G


(2) G + P = 30


Substituting (1) into (2) gives:


G + 5G = 30


6G = 30


G =5


So there are 5 green pencils.


Now using that in (1) gives us P = 5 x 5 = 25


So there are 5 green pencils and 25 purple pencils.
