0.3(r+2)=-0.1(-2-4)

Solution for 0.3(r+2)=-0.1(-2-4) equation:

Simplifying
0.3(r + 2) = -0.1(-2 + -4)

Reorder the terms:
0.3(2 + r) = -0.1(-2 + -4)
(2 * 0.3 + r * 0.3) = -0.1(-2 + -4)
(0.6 + 0.3r) = -0.1(-2 + -4)

Combine like terms: -2 + -4 = -6
0.6 + 0.3r = -0.1(-6)

Multiply -0.1 * -6
0.6 + 0.3r = 0.6

Add '-0.6' to each side of the equation.
0.6 + -0.6 + 0.3r = 0.6 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + 0.3r = 0.6 + -0.6
0.3r = 0.6 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.3r = 0.0

Solving
0.3r = 0.0

Solving for variable 'r'.

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