Answer:
is the algebraic expression to represent the situation.
Step-by-step explanation:
Given:
Some students equally share 2 baskets of apples.
Each basket has 12 apples.
To Find:
An algebraic expression to represent the situation = ?
Solution:
Let the number of students be x
The number of apple each one gets be y
then it is said that there are 12 apples in one basket.
So in two basket there will be
=> 
=> 24 apples
This 24 apples is to be shared among x students, so
Each student will get

Answer:
x = -1
Step-by-step explanation:
A graphical solution can avoid extraneous solutions. The attachment shows the one solution is x = -1.
__
Squaring both sides gives ...
x +5 = (x +3)² = x² +6x +9
Putting this in standard form, we have ...
x² +5x +4 = 0
(x +1)(x +4) = 0 . . . . . factor
x = -1 or -4 . . . . . . . . values of x that make the factors zero
__
Since we require the root to be non-negative, we must have ...
x +3 ≥ 0
x ≥ -3
The only solution that satisfies this requirement is x = -1. The solution x = -4 is extraneous. The solution is x = -1.
