Answer:
x=-7 y=3
Step-by-step explanation:
5x+10y=-5
-5x-y=32
9y=27
y=3
5x+10(3)=-5
5x+30=-5
5x=-35
x=-7

Step-by-step explanation:
-4 5
---- ---- = (7×5) ÷4
7 x
Lets find all the numbers..
x (1st number)
x + 2 ( 2nd number)
x + 4 (3rd number)
x + 6 (4th number)
x + 8 (5th number)
x + 10 (6th number)
Now add all those expressions and set them equal to 270 because that is the total.
x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 270
6x + 30 = 270
6x = 240
x = 40
Now we will substitute 40 for x in the expression of the second number.
x + 2
40 + 2
42
So the second number is 42
Hope this helps :)
