Question

Solve for d.
4d - 4 = 5d - 8

Answer 1

Answer: d = 4

Explanation:

4d - 4 = 5d - 8

+8 +8 (Add 8 to both sides)

4d + 4 = 5d

-4d -4d (Subtract 4d from both side)

d= 4

Answer 2

Explanation:

4d-4=5d-8

add 4 to both sides

4d=5d-4

subtract 5d from both sides

-d=-4

switch so d is positive

d=4
