Solve equation:<br> -3|d-5|=-6
gulaghasi [49]

Answer:

d = 7, 3

Step-by-step explanation:

First, you need to isolate the absolute value

-3|d - 5| = -6

divide both sides by -3:

|d - 5| = 2

break into 2 equations:

d - 5 = 2, d - 5 = -2

solve both equations and collect solutions:

d = 5 + 2, d = 5 - 2

d = 7, 3
