Answer:
=x
Step-by-step explanation:
Two can be the same and for the most that would be two $5 bills and the third would be a $1 bill so the most he could give her is $11
The first triangle does. That's the right answer.
-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
