distribute

-4+7(1-3m)

To distribute -4 within the parentheses, we multiply each term within the parentheses by -4:

-4 + 7(1) + 7(-3m)

Simplifying further, we have:

-4 + 7 - 21m

The final expression is -21m + 3.

To distribute the expression -4+7(1-3m), you need to multiply 7 by each term within the parentheses.

First, distribute the 7 to 1 by multiplying 7 by 1:
-4 + 7 * 1 = -4 + 7 = 3

Then, distribute the 7 to -3m by multiplying 7 by -3m:
7 * (-3m) = -21m

Putting it all together, the expression becomes:
3 - 21m
