Question

Solve for (d).

4d−4=5d−8

d= ?

Answer 1

Answer(s):

d= 4 (D=4) or 4=d (4=D)

Step-by-step explanation: You can solve it in 2 ways.

The
`1^(st)` way:

4d−4 = 5d−8

+4 +4

4d = 5d-4

-5d -5d

-1d = -4

/-1 /-1

d = 4

The
`2^(nd)`

4d−4 = 5d−8

+8 +8

4d+4 = 5d

-4d -4d

4 = 1d

/1 /1

4 = d
