To find the equivalence you need to simplify the expression to get
84x - 16y - 10.6
:)))
Answer:
B
Step-by-step explanation:
First add 7d to both sides:
-22 = 11d
Now divide by 11 both sides
-2 = d
You can work on either side of the equation, I used the right side for the variables because it was easier to add to positive numbers than dealing with negative numbers on the left side:
-7d -4d = 22
-11d =22
d = -2
either way you get the same answer :)
I would minus 2 from both sides of the equation so that it becomes:
