2(4 - 2r) = -2(r + 5)

First, divide both sides by -2. / Your problem should look like: -4 + 2r = r + 5
Second, regroup your terms. / Your problem should look like: 2r - 4 = r + 5
Third, add 4 to both sides. / Your problem should look like: 2r = r + 5  + 4
Fourth, add r + 5 + 4 to get r + 9. / Your problem should look like:2r = r + 9
Fifth, subtract r from both sides. / Your problem should look like: 2r - r = 9
Sixth, subtract 2r - r to get r. / Your problem should look like: r = 9

Answer: r = 9

The sum of two confescutive integers is at least 46. What is the least possibly pair of integers?
dezoksy [38]
An integer is a whole number. Sum means to add and since they are consecutive, there is only a difference of 1 between them.

1) 21 + 23: not consecutive
2) 23+24= 47: has to be at least 46
3) 22+23= 45: has to be at least 46
4) 24+25= 49: has to be at least 46

So we have two possibilities: either #2 or #4. Find least possible pair of integers.

x= first integer
x+1= second integer

x + (x+1) >= 46
2x + 1 >=46
2x>=45
x>=22.5

Answer:
The first integer has to be greater than or equal to 22.5. Since integers are whole numbers, round up to the next whole number. The least possible integers are #2) 23 and 24.

Hope this helps! :)
