0.2(d-6)+1.4d=1.6d-1.2

Solution for 0.2(d-6)+1.4d=1.6d-1.2 equation:

Simplifying
0.2(d + -6) + 1.4d = 1.6d + -1.2

Reorder the terms:
0.2(-6 + d) + 1.4d = 1.6d + -1.2
(-6 * 0.2 + d * 0.2) + 1.4d = 1.6d + -1.2
(-1.2 + 0.2d) + 1.4d = 1.6d + -1.2

Combine like terms: 0.2d + 1.4d = 1.6d
-1.2 + 1.6d = 1.6d + -1.2

Reorder the terms:
-1.2 + 1.6d = -1.2 + 1.6d

Add '1.2' to each side of the equation.
-1.2 + 1.2 + 1.6d = -1.2 + 1.2 + 1.6d

Combine like terms: -1.2 + 1.2 = 0.0
0.0 + 1.6d = -1.2 + 1.2 + 1.6d
1.6d = -1.2 + 1.2 + 1.6d

Combine like terms: -1.2 + 1.2 = 0.0
1.6d = 0.0 + 1.6d
1.6d = 1.6d

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

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

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