Identify a possible first step using the elimination method to solve the system and then find the solution to the system. 2x – 3
y = 6 3x – y = 2 A) Multiply first equation by 3 and second equation by 2, solution (0, 2). B) Multiply first equation by -3 and second equation by 2, solution (0, 2). C) Multiply first equation by 3 and second equation by 2, solution (-2, 0). D) Multiply first equation by -3 and second equation by 2, solution (0, -2).
The step multiply x by 2 in the first equation and subtract the second equation will NOT produce a system with the same solution. The entire equation must be multiplied by 2.
Given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.
The degree refers to the x to some exponent where the highest exponent is the degree. Degree: 3 The leading coefficient is the coefficient of the term we just found(of the highest exponent) Leading Coefficient: 1 The constant term is the term without an x in it. Constant Term: 1
