Solve for x: 2x + 20 = 26.

Answer and explanation

Correct answer: B. 3

  1. Step 1: Subtract 20 from both sides: 2x = 6. Step 2. Divide both sides by 2: x = 3. Answer: 3. Why not the others: 6: Subtracting 20 gives 6, but that still has to be divided by 2. 46: The 20 must be subtracted from both sides, not added. 4: That is one more than the value that satisfies the equation.
