Solve with elimination.

Answer:y=6.61,x=-6.46

Step-by-step explanation:

3x+7y=-26(×5)

5x+3y=-14(×3)

=15x+35y=-130

15x+9y=-42

subtracting the 2 equations =15x-15x+35y-9y=-130-(-42)

=26y=172

y=172÷26

y=6.61

substitute y in the first equation=3x+6.61=-26

3x=-26+6.61=-19.39

x=-19.39÷3

x=-6.46

Answer:

Step-by-step explanation:

Given expression is,

$\text{cot}A=\frac{1}{2}(\text{cot}\frac{A}{2}-\text{tan}\frac{A}{2})$

To prove this identity we will take the right side of the identity,

$\frac{1}{2}(\text{cot}\frac{A}{2}-\text{tan}\frac{A}{2})=\frac{1}{2}(\frac{1}{\text{tan}\frac{A}{2}}-tan\frac{A}{2})$

$=\frac{1}{2}(\frac{1-\text{tan}^2\frac{A}{2}}{tan\frac{A}{2}})$

$=\frac{1}{2}[\frac{2(1-\text{tan}^2\frac{A}{2})}{2tan\frac{A}{2}}]$

$=\frac{1}{2}(\frac{2}{\text{tan}A} )$ [Since $\text{tan}A=\frac{2\text{tan}\frac{A}{2}}{1-\text{tan}^2\frac{A}{2}}$ ]

= cot A

Hence right side of the equation is equal to the left side of the equation.
