Question 706524: Okay here's an example of a problem I need to solve and I can not figure it out with P.E.M.D.A.S I get really close but no sure answer can you work the problem out by showing work so I can follow how to do the rest of the problems I have like this?
3(5z-1)-2(z+1)=6(z+1)

3%285z-1%29-2%28z%2B1%29=6%28z%2B1%29 Start with the given equation.


15z-3-2z-2=6z%2B6 Distribute.


-5%2B13z=6z%2B6 Combine like terms on the left side.


13z=6z%2B6%2B5 Add 5 to both sides.


13z-6z=6%2B5 Subtract 6z from both sides.


7z=6%2B5 Combine like terms on the left side.


7z=11 Combine like terms on the right side.


z=%2811%29%2F%287%29 Divide both sides by 7 to isolate z.

Answer:

So the solution is z=11%2F7
