Answer:
1. x = y - 2
2. 2y = 2x
Step-by-step explanation:
1. Any number can fit x and y so long as x is 2 lesser than y and y is 2 more than x.
2. x and y can be any number so long as they are the same number.
Answer:
if you decrease 10 kg by 10% you get 9 kg
Divide the first equation by 2 and add the result to the second equation. This will eliminate x.
... (-4x -2y)/2 + (2x +4y) = (-12)/2 +(-12)
... 3y = -18 . . . . . collect terms
... y = -6 . . . . . . . divide by 3
Substitute this into either equation to find x. Let's use the second equation, where the coefficient of x is positive.
... 2x +4(-6) = -12
... 2x = 12 . . . . . . . . add 24
... x = 6 . . . . . . . . . . divide by 2
The solution is (x, y) = (6, -6).
When u think of multiples...think of multiplication tables...
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
and so on.....so ur multiples of 5 are 5,10,15..and so on
so multiples of 5 starting at 75 would be.....75,80,85,90,95,100...and so on....not sure how far ur supposed to count to...
