Hello from MrBillDoesMath!



Answer:

x = -11, y = 6


Discussion:

I don't understand the answer shown -- "Doesn't Exist" -- especially as part of the problem statement is not displayed,  BUT

-6x + 3y = 84     =>    divide both sides by 3

-2x + y = 84/3= 28

-2x + y = 28          (A)


Multiply X = -23 + 2Y by 2 to get

2x = - 46 + 4y      (B)

Adding (A) and (B) gives


(-2x + y ) + (2x) =  28 + (-46 + 4y) =>

y = 28 -46 + 4y =>                                      as -2x + 2x = 0

y = -18 + 4y =>

18 = 3y =>

y = 6

From (A)    -2x + (6) = 28 or -2x = 28 -6 = 22 so x = -11



Thank you,

MrB

Michael Chan leaves a dock in his motorboat and travels at an average speed of 9 mph toward the Isle of Shoals, a small island o
horsena [70]

Since the motor boat left the dock 2 hours before the tour boat, their meeting point will be 27 miles from the dock from which both boats departed after 3 hours.

<h3>What is the distance?</h3>

Distance is the movement of an object regardless of direction. The distance can be defined as the amount of length an object has covered, regardless of its starting or ending position

We know that r × t = d

r = rate of speed

t = time

d = distance

For the motor boat

9 × t = d = rate × time

For the tour boat

27 × (t - 2) = d = rate × time

When they both cover the same distance in the same amount of time, they will eventually cross paths.

They both cover the same d-mile distance, so:

9 ×t = 27 × (t - 2)

Simplify to get:

9 × t = 27 × t - 54

18 t = 54

t = 3

The motor boat will have traveled at 9 mph for 3 hours to make a distance of 9 × 3 = 27 miles.

The tour boat will have traveled at 27 mph for 1 hour to make a distance of 1 × 27 = 27 miles.

Since the motor boat left the dock 2 hours before the tour boat, their meeting point will be 27 miles from the dock from which both boats departed after 3 hours.

An equation is shown below: 5(2x-8) +15 = -15 write the steps you will use to solve the equation and explain each step
faust18 [17]

Answer:

5(2x-8)+15=-15

10x-40+15=-15

10x-25=-15

    +25   +25 (add 25 to both sides)

____________

10x=10

divide by 10 on both sides

x=1
