Answer: Aeva sold 69 red pins.

Step-by-step explanation:

Let x represent the number of pins with green beads that Aeva sold.

Let y represent the number of pins with red beads that Aeva sold.

Each pin with green beads sells for $3. Each pin with red beads sells for $2. She raised $312. It means that

3x + 2y = 312- - - - - - - - - - -1

The number of pins with green beads is 11 fewer than the number of pins with red beads. It means that

x = y - 11

Substituting x = y - 11 into equation 1, it becomes

3(y - 11) + 2y = 312

3y - 33 + 2y = 312

3y + 2y = 312 + 33

5y = 345

y = 345/5

y = 69

x = y - 11 = 69 - 11

x = 58

Identify the solution(s) of the system of equations, if any. -4x-2y=16 2y=-4x-16
Elodia [21]
-4x-2y = 16
2y = -4x-16

Get one variable alone on both equations

-4x - 16 = 2y
-4x - 16 = 2y

You'll realize that they're the same equation.
Use substitution

-4x-16 = -4x-16
0 = 0
x = all solutions

Use x = all solutions in an earlier equation to find y

-4x - 16 = 2y
SInce x can be all solutions y is also all solutions
y = all solutions
