The solution to the simultaneous equation is x = 1 and y = 3

<h3>How to solve simultaneous equation?</h3>

1 / 3 x + y = 10 / 3

2x + 1 / 4 y = 11 / 4

multiply equation one by 3 and multiply equation 2 by 4

Therefore,

x + 3y = 10

8x + y  = 11

hence,

x + 3y = 10

24x + 3y = 33

23x = 23

x = 23 / 23

x = 1

Therefore,

1 + 3y = 10

3y = 10 - 1

3y = 9

y = 9 / 3

y = 3

Simplify the trigonometric function
Alisiya [41]

Answer:

  a.  csc²θ

Step-by-step explanation:

You can use the identities ...

  1 +tan² = sec²

  cot = cos/sin

  sec = 1/cos

  csc = 1/sin

___

Then the expression becomes ...

  \cot^2{\theta}(1+\tan^2{\theta})=\cot^2{\theta}\sec^2{\theta}=\dfrac{\cos^2{\theta}}{\sin^2{\theta}\cos^2{\theta}}=\dfrac{1}{\sin^2{\theta}}\\\\=\boxed{\csc^2{\theta}}

\qquad \qquad\huge \underline{\boxed{\sf Answer}}

Let's solve ~

\qquad \sf  \dashrightarrow \:  \dfrac{2x - 1}{5}  =  \dfrac{x -  2}{2}

\qquad \sf  \dashrightarrow \: 2(2x - 1) = 5(x - 2)

\qquad \sf  \dashrightarrow \: 4x - 2 = 5x - 10

\qquad \sf  \dashrightarrow \: 5x - 4x = -2 + 10

\qquad \sf  \dashrightarrow \: x = 8

Value of x is 8
