Answer:
d= 0.33
Step-by-step explanation:
Get rid of the parenthesis first
9(5d-4) = -19 - 7d
45d -36= -19 -7d
Then get the variable to one side of the equation
52d -36= -19 (Add 7d to both sides of the equation to get rid of the -7d)
Then you need to isolate the variable. Do this by getting rid of the 36.
52d = 17
Divide both sides by 52 to get "x" by itself.
d= 17/52
d= 0.33
