Q. 2A12+4A=12+8A+185A 2 A-12+4 A=12+8 A+18-5 A
  1. Combine like terms: Step Title: Combine like terms on both sides\newlineConcise Step Description: Simplify both sides of the equation by combining like terms.\newlineStep Calculation: Left side: 2A+4A12=6A122A + 4A - 12 = 6A - 12. Right side: 12+18+8A5A=30+3A12 + 18 + 8A - 5A = 30 + 3A.\newlineStep Output: 6A12=30+3A6A - 12 = 30 + 3A
  2. Isolate variable A: Step Title: Move all terms involving AA to one side and constants to the other\newlineConcise Step Description: Isolate the variable AA on one side of the equation.\newlineStep Calculation: 6A3A=30+126A - 3A = 30 + 12\newlineStep Output: 3A=423A = 42
  3. Solve for AA: Step Title: Solve for AA\newlineConcise Step Description: Divide both sides by the coefficient of AA to solve for AA.\newlineStep Calculation: A=423A = \frac{42}{3}\newlineStep Output: A=14A = 14
