6.8+2(r-3.1)=0.3r+32.9

Solution for 6.8+2(r-3.1)=0.3r+32.9 equation:

Simplifying
6.8 + 2(r + -3.1) = 0.3r + 32.9

Reorder the terms:
6.8 + 2(-3.1 + r) = 0.3r + 32.9
6.8 + (-3.1 * 2 + r * 2) = 0.3r + 32.9
6.8 + (-6.2 + 2r) = 0.3r + 32.9

Combine like terms: 6.8 + -6.2 = 0.6
0.6 + 2r = 0.3r + 32.9

Reorder the terms:
0.6 + 2r = 32.9 + 0.3r

Solving
0.6 + 2r = 32.9 + 0.3r

Solving for variable 'r'.

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

Add '-0.3r' to each side of the equation.
0.6 + 2r + -0.3r = 32.9 + 0.3r + -0.3r

Combine like terms: 2r + -0.3r = 1.7r
0.6 + 1.7r = 32.9 + 0.3r + -0.3r

Combine like terms: 0.3r + -0.3r = 0.0
0.6 + 1.7r = 32.9 + 0.0
0.6 + 1.7r = 32.9

Add '-0.6' to each side of the equation.
0.6 + -0.6 + 1.7r = 32.9 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + 1.7r = 32.9 + -0.6
1.7r = 32.9 + -0.6

Combine like terms: 32.9 + -0.6 = 32.3
1.7r = 32.3

Divide each side by '1.7'.
r = 19

Simplifying
r = 19
