4 0

Here are a few doubles facts:

5+5=10
2+2=4
3+3=6

A double is simply a pair of identical numbers added together. There's a pair of doubles you can subtract 1 from to get 6+7, and there's a pair you can add 1 to get the same answer. What are those pairs?

Hint: If you take the example 3+4, you can either subtract 1 from the double 4+4 or add 1 to the double 3+3 to obtain your answer.

What is 3d+8=2d-7 is equations

fredd [130]

3d + 8 = 2d - 7 equals d = -15.

First, subtract 2d from both sides. Your problem should look like: 3d + 8 - 2d = -7.
Second, simplify 3d + 8 - 2d to get d + 8. Your problem should look like: d + 8 = -7.
Third, subtract 8 from both sides. Your problem should look like: d = -7 - 8.
Fourth, simplify -7 - 8 to get -15. Your problem should look like: d = -15, which is your answer.

Hopefully this helps, I'm not exactly sure what you meant by "is equations," but this is how you solve the problem.
