1 answer:
Blababa [14]3 years ago

Answer:

(4,6) is the solution.

Step-by-step explanation:

Given $ 4x + y = 10 $

Let the solution be $ (a,-6) $.

The solution to this line means it should satisfy the equation. Therefore, substituting this we get,

$ 4(a) - 6 = 10 $

$ \implies 4a = 16 $

Dividing by 4 throughout we get,

$ a = 4 $

Therefore, the solution is: (4,6)

➷ Just work with what is inside the parenthesis

Also, move around the terms to help it make more sense:

(cosA cosB - cosA cosB + sinA sinB + sinA sinB)

As you can see, the 'cosA cosB' would cancel out through subtraction.

Now we have this:

(sinA sinB + sinA sinB)

This is just two sets of sinA sinB so it can be written as:

(2 * sinA sinB)

Simply place the values outside the parenthesis back there to get the answer

SinA sinB = 1/2 * (2 * sinA sinB)

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^
