Answer: 35z⁶d¹¹

Make up a problem?

(-2x²yz)(3xy²z)(4xyz²) = (-2)(3)(4) x²⁺¹⁺¹y¹⁺²⁺¹z¹⁺¹⁺² = -24x⁴y⁴z⁴

First you would distribute the constant into the numbers in the parentheses. so
8z=8z+4
then you would combine like terms which in this case would result in a zero.
8z-8z=0 So the z would be zero or no solution.
