Find the solution of Equation: (3x-2)/(x+3)-1=(3x-3)/(x+1)-2
saveliy_v [14]

Answer:

Solution tends to infinity

Step-by-step explanation:

Given the expression

(3x-2)/(x+3)-1=(3x-3)/(x+1)-2

This can also be expressed as;

(3x-2)/x+2 = 3x-3/x-1

3x-2/x+2 = 3(x-1)/x-1

3x-2/x+2 = 3

Cross multiply

3x-2 = 3(x+2)

3x-2 =3x+6

Collect like terms

3x-3x =6+3

0x = 9

x = 9/0

x = infinity

Hence the expression had no solution. It tends to infinity

Sam entered three functions into a graphing calculator, y1 = x + 2, y2 = x2 + 2, and y3 = 2x. A portion of the table created by
V125BC [204]
For this case we have the following functions:
 y1 = x + 2

y2 = x ^ 2 + 2

y3 = 2 ^ x
 
 When x = 0 we have:
 For y1:
 y1 = 0 + 2

y1 = 2
 For y2:
 y2 = 0 ^ 2 + 2

y2 = 0 + 2

y2 = 2
 Therefore, we have to:
 y1 = y2


 When x = 5 we have:
 For y2:
 y2 = 5 ^ 2 + 2

y2 = 25 + 2

y2 = 27
 For y3:
 y3 = 2 ^ 5

y3 = 32
 Therefore, we have to:
 y2 \ \textless \ y3


 When x = -1 we have:
 For y1:
 y1 = -1 + 2

y1 = 1
 For y2:
 y2 = (-1) ^ 2 + 2

y2 = 1 + 2

y2 = 3

 For y3:
 y3 = 2 ^ {-1}

y3 = 1/2

y3 = 0.5
 Therefore, we have to:
 y3 \ \textless \ y1 \ \textless \ y2


 Answer:
 
When x = 0, y1 = y2
 
When x = 5, y2 <y3
 
When x = -1, y3 <y1 <y2
