b. Reasoning In finding the values of x and y in OKLMN, does it matter which variable you solve for first? Explain. M + 8 2x y + 2 Р y + 10 K N A. Yes; it is only possible to write an equation for x. Once you have found x, you can solve for y. B. Yes; it is only possible to write an equation for y. Once you have found y, you can solve for X. C. No; solutions to a system of equations do not depend on the method used to solve it. D. No; since x and y must be equal, you can solve for either variable first.
