Question

Answer two questions about Equations A and B: A. 2x1 = 5x B. -1 = 3x

Answer 1

Answer:

This is Equation B

Step-by-step explanation:

• Algebraic equations are mathematical equations that contain unknown variables.
• To get Equation B from Equation A, we add/subtract the same quantity to/from both sides. Option A is the correct option.
• Equation A is equivalent to Equation B
• Question 1: We are given equation A as:
• 2x - 1 = 5x .............Equation A
• To get Equation B from A, we would subtract 2x from both sides of the equation.
• 2x - 2x - 1 = 5x - 2x
• - 1 = 3x This is Equation B
• Question 2: Based on the previous answer,
• 2x - 1 = 5x  is equal to  -1 = 3x.
• Hence, both Equation A and Equation B are equivalent expressions.
• Therefore,
• To get Equation B from Equation A, we add/subtract the same quantity to/from both sides. Option A is the correct option.
• Equation A is equivalent to Equation B
