To eliminate a cariable in a system of equations, we multiply the variable by a factor that will make both coefficients of the variable to be equal.
Thus, we multiply the coefficient of y in the second equation by a factor that will make it equal to the coefficient of y in the first equation. i.e. multiply 1/2 by a factor that makes it equal to 3/4. and the factor is 3/2.
Therefore, the third option is the correct answer.

Answer:
<h3>The answer is option A</h3>
Step-by-step explanation:
Let the price of the room be p
Let the size of the room be s
To find the size of a kitchen that costs $3,824.00 we must first find the relationship between them
The statement
The price of tiling a room varies directly as the size of the room is written as
<h3>p = ks</h3>
where k is the constant of proportionality
when
p = $4,224.00
s = 264 square feet
Substitute the values into the expression to find k
That's
4224 = 264k
Divide both sides by 264
k = 16
So the formula for the variation is
<h3>p = 16s</h3>
when
p = 3824
s = 239
The final answer is
239 square feet

Determine its equivalent
<em>From the list of given options, the correct answer is</em>
This is shown as follows;
Multiply both sides by
Open Bracket
Subtract x from both sides
Multiply both sides by -1
Reorder
