(x + -0.02) equal to 0.0000 and 0.0000.

Subproblem 1

x + -0.02 = 0.0000 Simplifying x + -0.02 = 0.0000 Reorder the terms: -0.02 + x = 0.0000 Solving -0.02 + x = 0.0000 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.02' to each side of the equation. -0.02 + 0.02 + x = 0.0000 + 0.02 Combine like terms: -0.02 + 0.02 = 0.00 0.00 + x = 0.0000 + 0.02 x = 0.0000 + 0.02 Combine like terms: 0.0000 + 0.02 = 0.02 x = 0.02 Simplifying x = 0.02

Subproblem 2

x + -0.02 = 0.0000 Simplifying x + -0.02 = 0.0000 Reorder the terms: -0.02 + x = 0.0000 Solving -0.02 + x = 0.0000 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.02' to each side of the equation. -0.02 + 0.02 + x = 0.0000 + 0.02 Combine like terms: -0.02 + 0.02 = 0.00 0.00 + x = 0.0000 + 0.02 x = 0.0000 + 0.02 Combine like terms: 0.0000 + 0.02 = 0.02 x = 0.02 Simplifying x = 0.02
