Question

Which is a simplified form of the expression 4(2z – 1) – 5z?

Answer 1

First just solve the brackets. You know how to do that ?

Answer 2

Pratyush means: Use the distributive property to expand 4(2z-1). Can you do tht?

Answer 3

\[4(2z-1) - 5z = 8z -4 - 5z\]

Answer 4

4(2z – 1) – 5z
(8z-4) - 5z
... you can do the rest :)

Answer 5

Now solve the like terms to get your answer.

Answer 6

Pratyush: Yes, but don't you mean "combine like terms" to obtain the answer? "Solve" applies only when we're "solving an equation." 4(2z-1)-5z is not an equation; it's an expression. Many thanks for your input.
