8cosx+1/2-cosx = 3
Solve for angle in degrees

Step-by-step explanation:

Alright you will need to use PEMDAS for this

Parenthesis

Exponent

Multiplication

Division

Addition

Subtraction ( Take note of this )

Step 1

9(3x – 16) + 15 = 6x – 24 You will remove parenthesis here

27x-129=6x-24

Step 2

Then subtract 6x,

27x-129=6x-24

21x-129=-24

Step 3

Then you add 129 to the sides,

21x-129=-24

21x=105

After that, you divide the sides by 21  so that you can get your answer

5

So therefore, your answer will be x=5
