Question

Write the equation: 7 less than the product of a number z and 3 is equal to 4.
How would i write this into a equation?
help??

Answer 1

7<z3=4

Answer 2

product of number z and 3 is z*3=4

Answer 3

Woops,
in this case, `less than` is referring to the `subtraction` operation.

`more than` means to `add` an amount,
`less than` means to `take away` that amount.

Answer 4

So you start with your quantity 3z
and take 7 away from it,

3z-7
and equate that to 4,
3z-7 = 4
