Answer:
Step-by-step explanation:
Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Subtract 2/4 from both sides
x + 2/4 (-2/4) = 8/4 (-2/4)j
x = 8/4 - 2/4
Simplify
x = (8 - 2)/4
x = 6/4
Simplify. Change the improper fraction into mixed fraction
x = 6/4 = (4/4 + 2/4) = 1 2/4
1 2/4 simplified = 1 1/2
1 1/2 is your answer

Answer:
??????????????????? 3+1
Step-by-step explanation:
Cotx = cosx/sinx
cscx = 1/sinx
If we plug these into your equation we get:
(cosx/sinx)/(1/sinx) - 1
Dividing by a number is the same as multiplying by its reciprocal so it can be rewritten as:
(cosx/sinx)(sinx) - 1
The two sinx's cancel each other out so we end up with cosx - 1
