x+2y=-2
what is the answer
Answer:
2(3x+y=4)
1(x+2y=-2)
6x+2y=8
(-) x+2y=-2
5x=10

x=2
x+2y=-1
2+2y=-1
-2 -2
2y=-3
2
y=-3/2
Step-by-step explanation:
If there are 10 apples and you take 4, then the remaining are 6 apples.
We have,
Use the concept of subtraction.
a - b = c
Where if a is greater than b, the answer is positive and if a is less than b, the answer is negative.
Now,
Total number of apples = 10 _______(1)
Number of apples taken = 4 _______(2)
Use this formula to find the remaining apples.
Substitute (1) and (2).
Number of apples remaining.
= 10 - 4
= 6
Thus,
If there are 10 apples and you take 4, then the remaining are 6 apples.
