X+2y=6 2x+4y=12 I need to use substitution to solve, may anybody help?

lana66690 [7]

$x + 2y = 6$

$x = - 2y + 6$
$2( - 2y + 6) + 4y = 12$
then find y and plug that y value into one of the original equations to find x

Hope this helps!

James takes off from Cooma and flies 452 km due south. He then turns and flies N37°E until he is due east of Cooma. How far is J

yuradex [85]

Answer: $\mathbf{341 km}$

Step-by-step explanation:

Given

James takes off from Cooma and flies 452 km to south

after that he travels $37^{\circ}$ East of North to reach east of Cooma

Suppose he is $\mathbf{x}\ km$ from Cooma

Form the figure, it can be written

$\Rightarrow \tan37^{\circ}= \dfrac{x}{452}\\\\\Rightarrow x=452\tan 37^{\circ}\\\Rightarrow x=340.6\ km\approx 341\ km$

Thus, James is $\mathbf{341 km}$ east to initial position.
