Answer:

x = 4 and y = -1

Step-by-step explanation:

Given that,

6x+5y=19 ... (1)

2x+3y=5 ...(2)

We need to solve the above equations.

Multiply equation (2) by 3.

6x+9y=15 ...(3)

Subtract equation (1) and (3).

6x+5y-(6x+9y)=19-15

6x+5y-6x-9y = 4

-4y = 4

y = -1

Put the value of y in equation (2).

2x+3(-1)=5

2x-3=5

2x=8

x=4

So, the solution of the above equations are x = 4 and y = -1.

Represent the following sentence as an algebraic expression, where "a number" is the letter x.A number is subtracted from 2 .

Mariana [72]

In general, the statement 'a is subtracted from b' is written as

$b-a$

Therefore, 'A number is subtracted from 2' is written as,

$2-x$

The answer is 2-x

There are now 7 classrooms of 31 and 3 of 30.

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

A linear equation in mathematics is an equation that can be written as display style a 1x 1+ldots +a nx n+b=0, where x 1, dots, x n are the variables, and display style b, a 1, ldots, a n are the coefficients, which are frequently real integers.

<h3>According to the given information:</h3>

Madison, we first have to add 30 + 31 = 61.

How many times does 61 go into 307

Five,

because 61 x 5 = 305.

This means there are 5 of each classroom.

We still have two students left over, though, so they will have to be added to two of the 30 rooms,

so there are now 7 classrooms of 31 and 3 of 30.
