2x + 4y = 14
4x + y = 20......multiply by -4
----------------
2x + 4y = 14
-16x - 4y = -80 (result of multiplying by -4)
---------------add
-14x = -66....as u can see, ur y's cancel out
so ur answer is : 1st answer choice <==
** and just so u know, u could have multiplied the 1st equation by -2, and it would have cancelled out ur x's
<u>Given</u>:
The given equation is 
We need to determine the approximate value of q.
<u>Value of q:</u>
To determine the value of q, let us solve the equation for q.
Hence, Subtracting
on both sides of the equation, we get;

Subtracting both sides of the equation by 2q, we have;

Dividing both sides of the equation by -1, we have;

Now, substituting the value of
, we have;

Subtracting the values, we get;

Thus, the approximate value of q is 0.585
Hence, Option C is the correct answer.
It's visually better to make it an equation.
-1 3/5 ÷ -2/3
The answer is 39/10.
