What should be the first step in adding these equations to eliminate y? 3x + 4y = 8 + 6x – 2y = 9 a. multiply the top equation by 6. b. multiply the top equation by 2. c. multiply the bottom equation by 2. d. multiply the bottom equation by 3

(C) Multiply the bottom equation by 2.

Step-by-step explanation:

The given equation are:

                               (1)

and                         (2)

Now, in order to add these equations and eliminate y, we should multiply the bottom equation by 2, thus we have

                               (3)

                             (4)

Now, adding the above equations, we have

Now, substituting the value of x in equation (3), we have

Therefore, option (C) is correct.

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
