Answer:
36
Step-by-step explanation:
Total number of packages = 12
Each package contains 3 pens
SO we can write the equation as follows
3 * 12 = 36
so the total no of pens in a box = 36
3x + y = -3
-2x + y = 7
Use elimination method
Subtract both equations
5x = -10, x = -2
Plug in -2 for x (any equation)
3(-2) + y = -3
-6 + y = -3
y = 3
Solution: x = -2, y = 3
Or as a coordinate: (-2, 3)
9.08+x=25.08
-9.08 -9.08
x=16
3/4x=12
x4/3 x4/3
x=16
4.5x=72
/4.5 /4.5
x=16
