Question

A system of two equations is shown below. What will you need to multiply the

top equation by in order to solve this system using the elimination method?
x +2y = 11
6x + 4y = 34
O A. 2
Oo oo
O c. 4
O D. 6

Answer 1

Explanation:

eq1. x + 2y = 11

eq2. 6x + 4y = 34

------------------

Objective is to eliminate one of the variables, either x or y.

Let's eliminate y by multiplying the top equation with the number 2.

2x +4x = 22

Now multiply the bottom equation by -1

2x +4x = 22

-6x -4x = -34

------------------

Now add both equation and you will see that y will be eliminated.

So therefore, the answer is A.2
