Question

What is -7x-3(9-7x) if x=-1

Answer 1

The value of - 7x - 3(9 - 7x) = - 41

Step-by-step explanation:

We have,

- 7x - 3(9 - 7x)             ....... (1)

To find, the value of - 7x - 3(9 - 7x) = ?

Put x = - 1 in equation (1), we get

= - 7( - 1) - 3(9 - 7( - 1))

= 7 - 3(9 + 7)

= 7 - 3(16)

= 7 - 48

= - 41

Thus, the value of - 7x - 3(9 - 7x) = - 41
