Question

What are the steps in solving 4/(x+1)-3/(x+2)=1?

Answer 1

\[\frac{4}{x+1}-\frac{3}{x+2}=1\]\[\frac{4(x+2)-3(x+1)}{(x+1)(x+2)}\]

Answer 2

\[=1\]

Answer 3

\[\frac{4x+8-3x-3}{(x+1)(x+2)}=1\]

Answer 4

\[x+5=(x+1)(x+2)\]

Answer 5

\[x+5=x^2+3x+2\]\[x^2+2x-3=0\]

Answer 6

\[(x+3)(x-1)=0\]
x=-3
x=1
