Answer:
8 slices
Step-by-step explanation:
According to the given situation, the data is as follows
F = unknown number of fruits
Number of fruits ate = 7 slices
Total number of fruits = 15 slices
Here the equation that should be used is
7 slices + x = 15 slices
So, the x is
= 15 slices - 7 slices
= 8 slices
Basically we deduct the both the slices so that the difference between them could come and the same is to be considered

➷ Use the simultaneous equations method:
x - 4y = 6
3x + 4y = 10
Add these two equations together to cancel out 'y':
4x = 16
Divide both sides by 4:
x = 4
substitute this value into one of the equations:
(4) - 4y = 6
Subtract 4 from both sides:
- 4y = 2
Divide both sides by -4:
y = -0.5
