Answer:
d = -1
Step-by-step explanation:
combine like terms
add the coefficients(numbers with variables) together and add the integers together.
-14 d + 16 = -6d + 6 + 18 ------ add 6d on both sides
-8d + 16 = 6 + 18 ---- subtract 16 on both sides
-8d = 18 - 16 + 6
-8d = 2 + 6
-8d = 8 --- divide -8 on both sides
d = -1
