Question

How do you solve `24- 2d = 4`?

Answer 1

`d=10`

Explanation:

`24-2d=4`

Subtract `24` from `24` on the left and `24` from `4` on the right to result in:
`-2d=-20`
Divide both sides by `-2` (`(-2)/(-2)` on left) and `-20/-2` on left to get
`d=10`

Answer 2

`d=10`

Explanation:

Isolate the variable `d`:

`24-2d=4`

`24=2d+4`

`2d=20`

`d=10`

Answer 3

d=10

Explanation:

When you subtract 24, the -2d will stay negative. These kinds of problems use to always confuse me. Just think of -2d as its on thing. So like +24 and -2d. You subtract a positive number and add a negative number.

`24-2d=4`

`-2d=-20`

`d=10`
