1.4-1.6(d+6)=4.6

Solution for 1.4-1.6(d+6)=4.6 equation:

Simplifying
1.4 + -1.6(d + 6) = 4.6

Reorder the terms:
1.4 + -1.6(6 + d) = 4.6
1.4 + (6 * -1.6 + d * -1.6) = 4.6
1.4 + (-9.6 + -1.6d) = 4.6

Combine like terms: 1.4 + -9.6 = -8.2
-8.2 + -1.6d = 4.6

Solving
-8.2 + -1.6d = 4.6

Solving for variable 'd'.

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

Add '8.2' to each side of the equation.
-8.2 + 8.2 + -1.6d = 4.6 + 8.2

Combine like terms: -8.2 + 8.2 = 0.0
0.0 + -1.6d = 4.6 + 8.2
-1.6d = 4.6 + 8.2

Combine like terms: 4.6 + 8.2 = 12.8
-1.6d = 12.8

Divide each side by '-1.6'.
d = -8

Simplifying
d = -8
