There is no solution for two equations 2x – y = 7 and y = 2x + 3 .

<h3>What is an equation?</h3>

A statement that the values of two mathematical expressions are equal (indicated by the sign =).

Name different methods to solve the system of equations .

(1)The Graphing Method .

(2)The Substitution Method .

(3)The Linear Combination Method

(4)The Addition Method

(5)The Elimination Method.

(6)The Matrix Method .

The solution of two equations

2x – y = 7 and

y = 2x + 3

On solving the two equations by Substitution Method ,we get

2x-(2x+3) =7

⇒2x-2x-3=7

⇒0 -3 =7

⇒-3 =7

But since the numbers are not equal ,so we conclude that

-3≠7

Hence ,as x gets canceled and y value is substituted ,so as a result we get two numbers which are also not equal .

Hence, there is no solution for x and y .

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 376 people entered the park, a
tatiyna

Answer:180 adults were admitted.

Step-by-step explanation:

Let x represent the number of children that were admitted into the park.

Let y represent the number of adults that were admitted into the park.

The admission fee at the amusement park is $1.50 for children and $4 for adults.

The admission fees collected totaled 1,014.00 dollars. This means that

1.5x + 4y = 1014 - - - - - - - - - -1

On a certain day, 376 people entered the park. This means that

x + y = 376

Substituting x = 376 - y into equation 1, it becomes

1.5(376 - y) + 4y = 1014

564 - 1.5y + 4y = 1014

- 1.5y + 4y = 1014 - 564

2.5y = 450

y = 450/2.5 = 180

Substituting y = 180 into x = 376 - y, it becomes

x = 376 - 180 = 196
