Seven times the difference of x and 4 is -10

4vir4ik [10]

Answer:

In this equation x = 2

Step-by-step explanation:

First, it is easiest to convert these words to numbers. That would make it

4 - x · 7 = -10

First subtract 4 from both sides.

4 - x · 7 - 4 = - 10 - 4

Then you simplify.

-x · 7 = -14

Divide both sides by 7.

$\frac{-x(7)}{-7} = \frac{-14}{-7}$

Then you simplify that fraction to 2 and thats how you get your answer.
