Step-by-step explanation:
Hey, there!
Given, equations are,
2x+y=10.............(i)
-3x+y= -5...........(ii)
From equation (i)
y=10- 2x...........(iii)
Putting the value of "y" from equation (iii) in equation (ii).
-3x+y= -5
-3x + (10-2x)= -5
-3x + 10-2x= -5
- 5x = -15
![x = \frac{ - 15}{ - 5}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%2015%7D%7B%20-%205%7D%20)
Therefore, x= 3.
Now, putting the value of "x" in equation (iii).
y= 10- 2x
y= 10- 2×3
Therefore, y= 4.

Answer:
it's already in it's simplest form
Step-by-step explanation:
Yes, matter of fact, when you do something of "equal" meaning to both sides of an equation it will still hold.
