You can put this solution on YOUR website!
Just replace x = -2, y = -3, and z = -5 into the expression and simplify, i.e.\r

\n" ); document.write( "Identifying variables, constants, and coefficients is quite straightforward. A variable is simply a symbol or letter that represents a number (x,y,z in this case). A constant is a fixed number (-17 in this case), and a coefficient is a constant that is multiplied with a variable. \n" ); document.write( "
