Breanna has quarters, dimes, and nickels in her purse. she has 3 fewer nickles than dimes, but she has 2 more nickles than quart
zmey [24]
We base ourselves in the one piece of crucial evidence: She has 2 quarters.
-from the rest of the problem, we know that she has 2 more NICKEL'S than QUARTERS, 

(2 Quarters + 2 = 4 nickels)

she has 3 fewer nickels than dimes, 

DIME - 3 = Nickels

D - 3 = 4

D = 7

7 dimes
(70 cents)

4 nickels
(20 cents)

2 quarters
(25 cents)

115 cents
or $1.15

Use a system of linear equations with two variables and two equations to solve. A number is 9 more than another number. Twice
Troyanec [42]

9514 1404 393

Answer:

  (x, y) = (3, 12)

Step-by-step explanation:

Using the given variable definitions, we can write the equations ...

  y = x + 9

  2(x +y) = 30

__

Solving the second equation for y, we have ...

  y = 15 -x

Substituting this into the first equation gives ...

  15 -x = x +9

  6 = 2x . . . . . . . . . add x-9

  3 = x . . . . . . . . . . divide by 2

  y = 3+9 = 12 . . . . substitute into the first equation

The numbers are (x, y) = (3, 12).
