Verify each identity:<br> (tanx+tany)/(1-tanxtany)=(sinxcosy+cosxsiny)/(cosxcosy-sinxsiny),

Lapatulllka [165]

Solution:
(tanx + tany)/(1-tanxtany) is equal to the formula of tan(x+y)
sinxcosy + cosxsiny = is equal to the formula of sin(x+y)formula
cosxcosy - sinxsiny) = is equal to the formula of cos(x+y)

So this means that
tan(x+y) = sin(x+y)/cos(x+y)

Solve the simultaneous equation:<br> 5 x + 2 y = 25 <br> 5 x − y = 10

Liono4ka [1.6K]

Answer:

(x, y) = (3, 5)

Step-by-step explanation:

$5x+2y=25\\5x-y=10$

Solving by elimination here again, there are 2 good options available. Either multiply the whole bottom equation by -1 to cancel the x, or by 2 to cancel the y. I'll do the latter:

$5x+2y=25\\\\2(5x-y=10)\\10x-2y=20$

Add from top to bottom:

$\rightarrow (5x+10x)+(2y-2y)=25+20\\\rightarrow 15x=45\\\rightarrow x=3$

Now, with the value of x, solve for y in either of the equations. I'll choose the second one here:

$\rightarrow 5x-y=10\\\rightarrow 5(3)-y=10\\\rightarrow 15-y=10\\\rightarrow -y=-5\\\rightarrow y=5$

(x, y) = (3, 5)
