If you have 2y-2x=3

Mathematics
1 answer:
Illusion [34]3 years ago
5 0

Answer:

x=2, y=5 or (2,5)

Step-by-step explanation:

The elimination method is adding or subtracting two equations from each other to get rid of a variable.

I am going to get rid of y first.

2y-2x=3

-2y+5x=3

When you use elimination to add and subtract, you get the equation:

3x=6

Simplify for:

x=2

There are two ways to find y. The easier way is to plug x=2 back into one of the original equations and solve, or you can use elimination again. To use elimination to find y:

First we have to make it so that our x's will add or subtract to 0 in the two original equations by multiplying.

5 * (2y-2x=3) = 10y-10x=15

2 * (-2y+5x=3) = -4y+10x=15

Adding those two equations together will give us:

6y=30

Simplify:

y=5

A park guide plans the swan boat ride for 40 people. Each boat can carry 6 people at time. How do you interpret the remainder of
seropon [69]

Answer:

There would be 7 swan boat rides out of which 6 will carry 6 people each but the last swan boat ride carries 4 people. 2 more people can join the swan boat ride.

Step-by-step explanation:

We are given the following information in the question:

A park guide plans the swan boat ride for 40 people.

Total number of people = 40

Number of people that can ride in 1 boat = 6

Number of boats required =

\displaystyle\frac{\text{Total number of people}}{\text{Numberof people that can ride in 1 boat}}=\frac{40}{6} = 6\frac{4}{6}

This can also be represented with the modulo function which gives the remainder.

40 \mod(6) = 4

Thus, there would be 7 swan boat rides out of which 6 will carry 6 people each but the last swan boat ride carries 4 people.

2 more people can join the swan boat ride.
