Answer:
d=5,-1
Step-by-step explanation:
|2d-4| = 6
There are two solutions, one positive and one negative
2d-4 =6 and 2d-4 = -6
Add 4 to each side
2d-4+4 = 6+4 2d-4+4 = -6+4
2d = 10 2d =-2
Divide by 2
2d/2 =10/2 2d/2 = -2/2
d=5 d=-1
[tex]|2d-4|=6 [/tex]
Absolute value..
[tex]2d-4=6 \\ 2d-4=-6 [/tex]
Simplify..
[tex]2d=10 \\ 2d=-2 [/tex]
Simplify again..
[tex]d=5 \\ d=-1 [/tex]
Hope it helps!
