You need to solve a system of equations. You decide to use the elimination method. Which of these is not allowed? 2x - 3y = 12
suter [353]

Answer:

A.

Step-by-step explanation:

The Elimination Method is the method for solving a pair of linear equations which reduces one equation to one that has only a single variable.

If the coefficients of one variable are opposites, you add the equations to eliminate a variable, and then solve.

If the coefficients are not opposites, then we multiply one or both equations by a number to create opposite coefficients, and then add the equations to eliminate a variable and solve.

When multiplying the equation by a coefficient, we multiply both sides of the equation (multiplying both sides of the equation by some nonzero number does not change the solution).

So, option B is not allowed (it is not allowed to multiply only one part of the equation)

A manufacturer of skis offered chain discounts of 10/5/4 to many of its customers. Joe Jones ordered skis that had a total list
kati45 [8]
First, 
149,500 * .10 = 14,950
149,500 - 14,950 = 134,550

then,
134,550 * .05 = 6727.50
134,550 - 6727 = 127,822.55 
127,822.50 * .04 = 5112.90

trade discount = 14950 + 6727.50 + 5112.90 
26790.40
