Pls help me (ᗒᗣᗕ)՞
I don’t know

If i drew it correctly, then al would also equal 14 in., because the midsegment divides the line ab into 2, equal in length lines.therefore, al = lb 

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
