Question

Substitution and Elimination Methods Nathan solves the following system of equations using the elimination method. – 2x + 3y = 6 4.3 – 6y = -12 He chooses to eliminate the variable x. Which statement correctly describes his process and solution? A: Nathan multiplies – 2x + 3y = 6 by 2 and then adds the equations. He finds the result is a contradiction, so there is no solution Nathan multiplies – 2x + 3y = 6 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. B: Nathan multiplies -2.x + 3y = 6 by 2 and then adds the equations. He finds the result is an identity, so there are infinitely many solutions. C: Nathan multiplies -2x + 3y = 6 by 2 and then subtracts the equations. He finds the result is an identity, so there are many infinitely many solutions. ​
