You can put this solution on YOUR website!
To solve any equation, you can use PEMDAS (Order of Operations) backwards. First get rid of any subtraction and addition.
\n" ); document.write( "Add 19 to both sides. 3z-19+19=173+19 --> 3z=192
\n" ); document.write( "Then get rid of any multiplication and division.
\n" ); document.write( "Divide both sides by 3. 3z/3=192/3 --> z=64
\n" ); document.write( "Finally, plug your answer back in to make sure you did it right.
\n" ); document.write( "3(64)-19=192-19=173 We have the right answer! :-) \n" ); document.write( "
