Final answer:

The two-column proof method was used to solve for X in two equations, yielding solutions of X=12 for the first equation and X=8 for the second equation through simple algebraic manipulations.

Step-by-step explanation:

To solve the given equations for the variable X using the two-column proof method, let's proceed step by step.

Equation A: 6(x - 3) + 22 = 4x + 10

  1. Distribute 6 into (x - 3): 6x - 18 + 4 = 4x + 10
  2. Combine like terms: 6x - 14 = 4x + 10
  3. Subtract 4x from both sides: 2x - 14 = 10
  4. Add 14 to both sides: 2x = 24
  5. Divide both sides by 2: x = 12

Equation B: (4x + 1) / 3 = 11

  1. Multiply both sides by 3 to eliminate the denominator: 4x + 1 = 33
  2. Subtract 1 from both sides: 4x = 32
  3. Divide both sides by 4: x = 8

These steps clearly demonstrate how to solve for X in both equations using straightforward algebraic manipulations, which fall into the category of linear equations and adhere to principles in solving equations.
