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.

-2x+3 &gt; x +24<br><br> Show steps how you got your solution
nalin [4]
- 2x + 3 > x + 24

First we must get all variables on the same side and constants on the opposite side. To do so we subtract x from the right and the left. Then subtract 3 from both sides as well. 

- 2x - x > 24 - 3 

Now we combine like terms:

- 3x > 21

We must isolate the variable x. In order to do so, we divide both sides by - 3. When you divide by a negative number, you must also flip the inequality so the greater than becomes a less than. 

x < 21 / - 3

x < - 7 is your answer.
