1 Question: 5/x- 1= 1/x+3

5(x+3)=x- 1

5x+ 15=x- 1

5x-x=- 15- 1

4x=- 16

x=-4

Question 2: 1-x/2-x minus 3/x-2=2 multiply both sides by x-2.

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

x-4=2x-4

2x-x=4-4

x=0

Question 3: 2/x+ 1 minus 1/x- 1=4x/x? Multiply both sides of-1 (x+ 1)(x- 1)

2(x- 1)-(x+ 1)=4x

2x-2-x- 1=4x

x-3=4x

4x-x=-3

3x=-3

x=- 1

Question 4: 2/x+3 plus 3/2=7/2x+6 times 2(x+3).

4+3(x+3)=7

3x+9+4=7

3x=7- 13

3x=-6

x=-2
