The given expression : -8.2d + 28.1 = 3.6d

Simplify the expression for the d :

-8.2d + 28.1 = 3.6d

Subtract 3.6d on both side of the equation

-8.2d -3.6d + 28.1 = 3.6d -3/6d

-11.8d + 28.1 = 0

Subtract 28.1 on both side :

-11.8d + 28.1 - 28.1 = -28.1

-11.8d = -28.1

Multiply both side by ( -1)

(-1) ( -11.8d) = (-1)(-28.1)

11.8d = 28.1

Divide both side by 11.8

11.8d/11.8 = 28.1/11.8

d = 2.38

Answer : d = 2.38
