Answer:
d = [tex]\frac{8c}{33}[/tex]
Step-by-step explanation:
6(2c + 3d) = 5(4c - 3d)
6(2c) + 6(3d) = 5(4c) - 5(3d) distribute out the terms
12c + 18d = 20c - 15d
18d + 15d = 20c - 12c get all like terms onto the same side
33d = 8c
d = [tex]\frac{8c}{33}[/tex] divide by 33 to isolate the d variable
