X+2y=23 5x+10y=55 solve please

1 answer:

6 0

X+2y=23
X=-2y +23
Plug this in for x in the second equation

5(-2y + 23) + 10y = 55
-10y + 115 + 10y = 55

The -10y + 10y cancel out, so there is no solution

Hope this helps!

(sin Θ − cos Θ)^2 − (sin Θ + cos Θ)^2

More generally, we have

$(a-b)^2-(a+b)^2=(a^2-2ab+b^2)-(a^2+2ab+b^2)=-4ab$

so that

$(\sin\theta-\cos\theta)^2-(\sin\theta+\cos\theta)^2=-4\sin\theta\cos\theta=-2\sin2\theta$
