HELP PLEASE!

Mathematics
1 answer:
IrinaVladis [17]3 years ago
7 0

Answer: x = - 2

y = 0

Step-by-step explanation:

The given system of linear equations is expressed as

x + 4y = - 2 - - - - - - - - - - - - - 1

- 5x + 5y = 10- - - - - - - - - - - - - 2

We would eliminate x by multiplying equation 1 by 5 and equation 2 by 1. It becomes

5x + 20y = - 10

- 5x + 5y = 10

Adding both equations, it becomes

25y = 0

Dividing both sides by 25, it becomes

y = 0/25 = 0

Substituting y = 0 into equation 1, it becomes

x + 4 × 0 = - 2

x = - 2

The system of equations have only one solution.

How do i find the value of a variable?
photoshop1234 [79]

To find the value of a variable you must know the basics of pre-Algebra.


Example:


2x+9=39


To find he answer of this you must subtract 9 from both sides

Then you are left with…


2x=30

Since 2x=30 means 2 times x equals 30

You can divide 2 from both sides to find the answer

Which is…

x=15

Help me please I don't know how to do this.
djyliett [7]
Hey there.

If the decimal point is .500 and up, we will be rounding up. If it is .499 and lower, we will be rounding down.
Now let’s look at the numbers.
2.500 g can be rounded up, so we’ll make that 3.000 g.
5.000 g is going to stay the same, since the decimal point is .000
2.268 g will be rounded down, making it 2.000 g
5.670 will be rounded up and will become 6.000 g
And finally, 11.340 g will be rounded down to 11.000 g.

Hope this helps!
