Hello Brainly User,

I will walk you threw to solve this problem..

Solve : 2x+3 = 0

Subtract 3 from both sides of the equation :

2x = -3

Divide both sides of the equation by 2:

x = -3/2 = -1.500

Solve : x-7 = 0

Add 7 to both sides of the equation :

x = 7

So x can equal 7 or -3/2

Hope i helped i was glad to help and i hope you have a great rest of your day!

Answer:

15 nickels
3 dimes

Step-by-step explanation:

Let d represent the number of dimes Molly has. Then she has 18-d nickels, and the total value (in cents) of her coins is ...

5(18 -d) +10d = 105

5d +90 = 105 . . . . . . simplify

5d = 15 . . . . . . . . . . . subtract 90

d = 3 . . . . . . . . divide by 5; number of dimes

18-d = 15 . . . . . number of nickels

Molly has 3 dimes and 15 nickels.
