Multiply by a creative 1

tester97 · Answer

creative one? D: my teacher doesnt teach me these things

luigi0210 · Answer

I meant multiply by the common denominator. 
$$\Large \frac{ 2 }{ x+3 }*(x(x+3))-\frac{ 1 }{ x }*(x(x+3))=\frac{ -6 }{ x(x+3) }*(x(x+3))$$
Cancels leaving: 
$$\LARGE 2x-(x+3)=-6$$

Darn it, but you should of stopped me.. the domain is that x can't equal -3.. just noticed ._.
