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
