Answer: the system of linear equations has no solutions.

Step-by-step explanation:

The given system of linear equations is expressed as

2x -3y =1 - - - - - - - - - - - - -1

-4x+6y=-4 - - - - - - - - - - - - - 2

We would eliminate x by multiplying equation 1 by 2 and equation 2 by 1. It becomes

4x - 6y = 2

- 4x + 6y = - 4

Adding both equations, it becomes

4x - 4x - 6x + 6x = 2 - 4

0 = -2

Therefore, there is no solution to the system of linear equations

Answer:

No solution

Step-by-step explanation:

Given equations are:

$2x-3y=1$ ---------------------(1)

$-4x+6y=-4$ -------------------(2)

Multiplying equation 1 by 2:

$4x-6y=2$ ---------------------(3)

Adding equations (2) and (3):

0=-2

This is an impossible equality.That means that there are no solutions to the given system of linear equations.

Simplify the expression (7x+1/2)+(6x-9 1/2)

monitta

To make this easier to read, I'll be substituting 1/2 for .5; they mean the same thing, but it's less confusing to type it in its decimal form.
7x + .5 + 6x - 9.5
Combine like terms (x's can be added together, and so can reg. numbers)
(7x + 6x) + (.5 - 9.5)
13x - 9

Solve differential equation. Just explain the first 2 steps

lutik1710 [3]

(1) will write us of the following form

$\dfrac{dy}{dx}+y^2\sin x=0\\ \\
$

(2) [do not it need explanation]

$\dfrac{dy}{dx}=-y^2\sin x\\ \\
$

(3) Left place variable "y" and right place, variable "x" like this

$\dfrac{dy}{y^2}=-\sin x\, dx\\ \\$

(4) Integrate both members

$\displaystyle
\int \dfrac{dy}{y^2}=\int-\sin x\, dx\\ \\$

(5) Solve us the integrals

$-\dfrac{1}{y}= \cos x+C$

(6) Isolate variable "y"

$\boxed{y=-\dfrac{1}{\cos x+C}}$

C: any cosntant

2 hamburger + 1 milk =5

1 hamburger + 2 milk =5-.25

1 hamburger + 2 milk =4.75

multiply this by -2

-2hamburger + -4 milk =-9.5

add the first equation

-2 hamburger + -4 milk =-9.5

2 hamburger + 1 milk =5

---------------------------------------

-3 milk = -4.5

divide by -3

milk = 1.50

Answer: milk $1.50
