(ax+ 1)b=a

b=a/(ax+ 1)

2.x=2(x-3)+a

If roots grow, then a=-9.

3.3/x+ 1 or 3/(x+ 1)

The first one is 1.2.3.

The second is 0. 1.2.

4. Multiply the left and right by x 2 (x+ 1) to get it.

3x^2-2x=5

(3x-5)(x+ 1)=0

X=5/3 and-1

5.(x-2)^2+(y+3)^2=0

x=2，y=-3

4+24+36/4-36= 1

And can you write the title clearly? Put a bracket on the denominator.
