If 3x − (7 − x) = 29, find the value of 6x.


Hint:

Rewrite 3x − (7 − x) as

3x + −1(7 − x)

and then use the Distributive Property to simplify.

6x = 45

6x = 60

6x = 46

6x = 54

Respuesta :

Answer:

54

Step-by-step explanation:

3x -(7-x) = 29       remove the parens

3x - 7 + x = 29     simplify

4x -7 = 29            add 7 to both sides of the equation

4x = 36            divide by

x = 9

then 6x = 6 * 9 = 54
