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 - <em>x </em>· 7 = -10
First subtract 4 from both sides.
4 - <em>x</em> · 7 - 4 = - 10 - 4
Then you simplify.
-<em>x ·</em> 7 = -14
Divide both sides by 7.

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