Which equation is equivalent to y=−2x+5y = -2x + 5?

A

2x+y=52x + y = 5

B

2x−y=52x - y = 5

C

x+2y=5x + 2y = 5

D

2x+y=−52x + y = -5

Correct Answer: A

Choice A is the correct answer. Rearrange.

  1. Add 2x: 2x+y=52x + y = 5.

💡 Strategic Tip: Moving a term across the equals sign changes its sign.

Choice B is incorrect because sign error on y. Choice C is incorrect because coefficients swapped. Choice D is incorrect because sign error on constant.
