The students wanted to go on a field trip.
Declarative, imperative, exclamatory, interrogative

declarative

Explanation:

This is declarative since a declaration is being made. There are no questions or exclamations nor commands.

Explanation:

It's declarative. It makes a statement.

It's not imperative. It does not give advice nor does it give a command.

It's not exclamatory. Something that exclaims like Wow Batman! is exclamatory.

It is not interrogative, which asks a question.

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4
