When solving this system of linear equations with the elimination method, you can multiply the bottom equation by 3.

Still the correct answer on APEX as of 4/29/19.

The correct option is A.

Explanation:

The system of equations is,

When solving this system of linear equations with the elimination method, we can multiply the bottom equation by 3.

This step works because according to the multiplication property of equality,

If,

        ... (1)

Multiplied both side by m then,

   ..... (2)

Then (1) and (2) are equivalent equations.

So, by multiplication property of equality, the second equation can be multiply by 3.

Therefore, he correct option is A.

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
