Solution for 0.2(X+3)-0.4(X+3)=-0.2-0.6 equation:

Simplifying
0.2(X + 3) + -0.4(X + 3) = -0.2 + -0.6

Reorder the terms:
0.2(3 + X) + -0.4(X + 3) = -0.2 + -0.6
(3 * 0.2 + X * 0.2) + -0.4(X + 3) = -0.2 + -0.6
(0.6 + 0.2X) + -0.4(X + 3) = -0.2 + -0.6

Reorder the terms:
0.6 + 0.2X + -0.4(3 + X) = -0.2 + -0.6
0.6 + 0.2X + (3 * -0.4 + X * -0.4) = -0.2 + -0.6
0.6 + 0.2X + (-1.2 + -0.4X) = -0.2 + -0.6

Reorder the terms:
0.6 + -1.2 + 0.2X + -0.4X = -0.2 + -0.6

Combine like terms: 0.6 + -1.2 = -0.6
-0.6 + 0.2X + -0.4X = -0.2 + -0.6

Combine like terms: 0.2X + -0.4X = -0.2X
-0.6 + -0.2X = -0.2 + -0.6

Combine like terms: -0.2 + -0.6 = -0.8
-0.6 + -0.2X = -0.8

Solving
-0.6 + -0.2X = -0.8

Solving for variable 'X'.

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

Add '0.6' to each side of the equation.
-0.6 + 0.6 + -0.2X = -0.8 + 0.6

Combine like terms: -0.6 + 0.6 = 0.0
0.0 + -0.2X = -0.8 + 0.6
-0.2X = -0.8 + 0.6

Combine like terms: -0.8 + 0.6 = -0.2
-0.2X = -0.2

Divide each side by '-0.2'.
X = 1

Simplifying
X = 1
