Question

Select the correct choices that belong in the blank for the system of equations shown below.

24x - 39 = 165

-6x +13y = -51

In order to solve this system by elimination, Stacy ____________ by ______. Then, when she adds the equations together, the x terms will cancel.

Question 4 options:

multiplies the second equation; -4

multiplies the first equation; 4

multiplies the second equation; 4

multiplies the first equation; -4

Answer 1

To solve by elimination one term needs to cancel with the other.

If we look at the second equation we see that we can change from 6 to 24 by a multiplication of 4.

`The opposite of 24 is -24`

So we would `multiply the second equation by 4` to get -24. This will cancel out the terms.
