Answer:
![\huge\boxed{\sf \{(-2,1)\}}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5Csf%20%5C%7B%28-2%2C1%29%5C%7D%7D)
Step-by-step explanation:
Given equations:
y = x + 3
y = -x - 1
By comparing the above equations, we get:
x + 3 = -x - 1
Add x to both sides
<h3>x + x + 3 = -1 </h3><h3>2x + 3 = -1</h3>
Subtract 3 to both sides
2x = -1 - 3
2x = -4
Divide 2 to both sides
x = -4/2
<h3>x = -2</h3>
Substitute x = -2 in first equation.
y = x + 3
y = -2 + 3
<h3>y = 1</h3>
So,
<h3>Solution Set = {(x,y)}={(-2,1)}</h3>
![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
The answer is.
![n = \frac{16}{5}](https://tex.z-dn.net/?f=n%20%3D%20%20%5Cfrac%7B16%7D%7B5%7D%20)
And if you need it on decimal form, it would be,
![3.2](https://tex.z-dn.net/?f=3.2)
An equation is formed of two equal expressions. The solution of the equation is 41.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The solution of the equation,
x + 21 = 62
x = 62 - 21
x = 41
Hence, the solution of the equation is 41.
