0.1=0.2(x+3)

Solution for 0.1=0.2(x+3) equation:

Simplifying
0.1 = 0.2(x + 3)

Reorder the terms:
0.1 = 0.2(3 + x)
0.1 = (3 * 0.2 + x * 0.2)
0.1 = (0.6 + 0.2x)

Solving
0.1 = 0.6 + 0.2x

Solving for variable 'x'.

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

Add '-0.2x' to each side of the equation.
0.1 + -0.2x = 0.6 + 0.2x + -0.2x

Combine like terms: 0.2x + -0.2x = 0.0
0.1 + -0.2x = 0.6 + 0.0
0.1 + -0.2x = 0.6

Add '-0.1' to each side of the equation.
0.1 + -0.1 + -0.2x = 0.6 + -0.1

Combine like terms: 0.1 + -0.1 = 0.0
0.0 + -0.2x = 0.6 + -0.1
-0.2x = 0.6 + -0.1

Combine like terms: 0.6 + -0.1 = 0.5
-0.2x = 0.5

Divide each side by '-0.2'.
x = -2.5

Simplifying
x = -2.5
