Solving for variable 'x'.

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

Add '-12.5' to each side of the equation.
12.5 + -12.5 + x = 12.419742348 + -12.5

Combine like terms: 12.5 + -12.5 = 0.0
0.0 + x = 12.419742348 + -12.5
x = 12.419742348 + -12.5

Combine like terms: 12.419742348 + -12.5 = -0.080257652
x = -0.080257652

Simplifying
x = -0.080257652

Subproblem 2
x + 12.5 = -12.419742348

Simplifying
x + 12.5 = -12.419742348

Reorder the terms:
12.5 + x = -12.419742348

Solving
12.5 + x = -12.419742348

Solving for variable 'x'.

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

Add '-12.5' to each side of the equation.
12.5 + -12.5 + x = -12.419742348 + -12.5

Combine like terms: 12.5 + -12.5 = 0.0
0.0 + x = -12.419742348 + -12.5
x = -12.419742348 + -12.5
