## anonymous one year ago Points A,B, and C are collinear. Point B is between A and C. Solve for x AC=3x+3, AB= -1+2, and BC= 11

thanks for sharing that

AB = -1+2?

3. anonymous

-1+2x

anyhow |dw:1442015881289:dw| $$\begin{cases} AC=3x+3\\ AB=-1+2x\\ BC=11 \end{cases} \\ \quad \\ AC-AB=BC\implies (3x+3)-(-1+2x)=11$$ solve for "x"

Are you sure you didn't miss anything in AB=-1+2 ? It doesn't look right to me. It would have been written AB=1 @Ryan00
