The solution of the system of equation is (-7, -2).
<h2>Given</h2>
The system of the equations;

From equation 1

Substitute the value of y in equation 1

The value of x= 2 is rejected because x = 2 not satisfy the equation.
Substitute 2 for the value of x in equation II
y − x = 5
y – 2 = 5
y = 5 +2
y = 7 (x =2, y =7) … Not included in the options
If x = -7
Substitute the value of x = -7 in the equation

Hence, the solution of the system of equation is (-7, -2).

This is because slope intercept from is "Y= mx+b" :)
Answer:
-3c
Step-by-step explanation:
The given expression is:

We need to simplify this expression. The rational expression in the denominator can be multiplied to numerator by taking its reciprocal as shown below:

Thus, the given expression in simplified form is equal to -3c
Yo sup??
cosx>0 in the 1st and 4th quadrant.
tanx>0 in the 1st and 3rd quadrant.
therefore the common solution is x lies in 1st quadrant.
Hence the correct answer is option A.
Hope this helps
