Answer:

x=3, y=-1

Step-by-step explanation:

We know that lcm(7, 2)=14, so we need to multiply equation 1 by 2.

This gives 2(4x-7y)=2(19), which simplifies to 8x-14y=38.

We know that lcm(2, 7)=14, so we need to multiply equation 2 by 7.

This gives 7(3x-2y)=7(11), which simplifies to 21x-14y=77.

Aha! Now we have a path to the solution!

We can subtract the first equation from the second to eliminate y.

This gives (21x-14y)-(8x-14y)=(77)-(38), which simplifies to 13x=39.

We can then divide by 3 to obtain x=3!

Then, we plug x=3 into the second equation to get 3(3)-2y=11.

We can subtract 9 from both sides to get -2y=2.

We then divide by -2 to obtain y=-1.

So, x=3 and y=-1, and we're done!

Solve the problem.

Answer:

There will be 90 ways to reach Greenup from Charleston.

Step-by-step explanation:

<em>Option C: 90 is correct.</em>

Let's name all the ways and try to visualize the roads.

C = Charleston

M = Mattoon

T = Toledo

G = Greenup

Task = Charleston to Greenup. How many different ways to reach?

    1            1          

    2           2           1

C   3     M   3   T      2   G

     4           4           3

     5           5

                   6

So, Refer to this above diagram.

If we Start from C then go to 1 and then go to M and then go to 1 and then go to T and then go to 1 and then go G.

If you notice, in this single possibility we have 3 ways: C to 1 to M, M to 1 to T, T to 1 to G.

It means we will have: 5 x 6 x 3 = 90 number of ways to reach greenup from Charleston.
