2(v-h)-k=r

Solution for 2(v-h)-k=r equation:

Simplifying
2(v + -1h) + -1k = r

Reorder the terms:
2(-1h + v) + -1k = r
(-1h * 2 + v * 2) + -1k = r
(-2h + 2v) + -1k = r

Reorder the terms:
-2h + -1k + 2v = r

Solving
-2h + -1k + 2v = r

Solving for variable 'h'.

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

Add 'k' to each side of the equation.
-2h + -1k + k + 2v = k + r

Combine like terms: -1k + k = 0
-2h + 0 + 2v = k + r
-2h + 2v = k + r

Add '-2v' to each side of the equation.
-2h + 2v + -2v = k + r + -2v

Combine like terms: 2v + -2v = 0
-2h + 0 = k + r + -2v
-2h = k + r + -2v

Divide each side by '-2'.
h = -0.5k + -0.5r + v

Simplifying
h = -0.5k + -0.5r + v
