Solve y=5x-8 and y=6x+3 by elimination

Answers

$\left \{ {{y=5x-8} \atop {y=6x+3}} \right.$

Arrange equation variables for elimination :

$\left \{ {{y-5x=-8} \atop {y-6x=3}} \right.$

y - 6x = 3
- y - 5x = -8
______________
-x = 11

For y :

y - 6 x = 3

y - 6 ( - 11 ) = 3

y + 66 = 3

y = 3 - 66

y = -63

x = - 11 y = -63

6.04 kilometers

Step-by-step explanation:

First, by AA triangle similarity theorem, we know that the two triangles are equal.

So, we can set up a ratio

3,500/2000=4200/x

cross multiplying, we get

3500x=4200*2000

and simplifying, we get x=2400

the distance will be 2,400+4,200=6600 yards

converting to kilometers,

6600*0.0009144=6.04
