You are given the system of equations to solve by the elimination method, which is an incorrect step that will not produce a system with the same solution? 3x + 3y = 4 18x − 9y = 12 a) multiply the first equation by 6 and subtract the second equation b) multiply the first equation by −6 and add the second equation c) multiply 3x by 6 in the first equation and subtract the second equation d) add 2 times the first equation and −1/3 times the second equation eliminate

C) Multiply 3x by 6 in the first equation and subtract the second equation.

Step-by-step explanation:

We have been given a system of equations. and . We are asked to choose the "incorrect" step that will make "not" produce a system with the same solution.

Let us see our give choices one by one.

A) multiply the first equation by 6 and subtract the second equation.

When we will multiply 1st equation by 6, the coefficient of x would be 18. When we will subtract 2nd equation the both x's will cancel out. Therefore, option A is correct.

B) multiply the first equation by −6 and add the second equation.

When we will multiply 1st equation by -6, the coefficient of x would be -18. When we will add 1st equation to 2nd equation the both x's will cancel out. Therefore, option B is correct as well.

C) Multiply 3x by 6 in the first equation and subtract the second equation.

We need to remember that we cannot multiply only one term of equation by some quantity as it will make the whole equation false, therefore, option C is incorrect.
