Answer:
Number of coins.
Step-by-step explanation:
You mean quantity?
The amount of or number of items (in this case coins).
Isolate the variable by dividing each side by factors that don't contain the variable.
x= 13/4 - y/4
If you are solving for x (only)
X = 45/4 - y/4
If you are solving for y (only)
Y= 45- 4x
2x²-6x+8=0
x²-3x+4=0
D=b²-4ac=9-16=-7
x=(3+/-i√7)/2
correct answer is the last one
