Answer:
2 Items
Step-by-step explanation:
5 markers -------> $6.55
4 markers -------> x
y= -4x + 54
4x + y =54
-4x -4x
y = -4x +54
-z+4=-4
First, you want to move the positive four to the other side to isolate the variable.
-z=-8
You cannot have a negative variable, so divide both sides by 1.
-z/1=-8/1
Your answer would be:
Z=8
