6=3+5(d-z)

Solution for 6=3+5(d-z) equation:

Simplifying
6 = 3 + 5(d + -1z)
6 = 3 + (d * 5 + -1z * 5)
6 = 3 + (5d + -5z)

Solving
6 = 3 + 5d + -5z

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-5d' to each side of the equation.
6 + -5d = 3 + 5d + -5d + -5z

Combine like terms: 5d + -5d = 0
6 + -5d = 3 + 0 + -5z
6 + -5d = 3 + -5z

Add '-6' to each side of the equation.
6 + -6 + -5d = 3 + -6 + -5z

Combine like terms: 6 + -6 = 0
0 + -5d = 3 + -6 + -5z
-5d = 3 + -6 + -5z

Combine like terms: 3 + -6 = -3
-5d = -3 + -5z

Divide each side by '-5'.
d = 0.6 + z

Simplifying
d = 0.6 + z
