Answer:

x = -3/10

Step-by-step explanation:

Solve for x by substituting y = 3x into the other equation:

2x - 4y = 3

2x - 4(3x) = 3

Simplify and solve for x:

2x - 12x = 3

-10x = 3

x = -3/10

So, x = -3/10

Step-by-step explanation:

Given

$Desc = 20.6\ metres$

$Asc = 5\frac{7}{10}\ metres$

Required

Determine the depth

The depth is the distance between the two distances as follows'

$Depth = |Desc - Asc|$

Substitute values

$Depth = |20.6 - 5\frac{7}{10}|$

Convert fraction to decimal

$Depth = |20.6 - 5.70|$

$Depth = |14.9|$

$Depth = 14.9\ metres$
