Question 287457
Your original equation was {{{ 3(z-2)=2(z-1) }}}
The first step is to distribute both sides of the equation:
{{{ 3z-6=2z-2 }}}
The next step to isolate the variables on one side and the others to the other side.

Subtract 2z on both sides: {{{ z-6=-2 }}}

Add 6 on both sides: {{{ z=4 }}}

The Answer: z is equal to 4. I hope this helps! :]
