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
