I think the x have to be around 5.28 or 5.29.
Sorry if it is incorrect.
Here how you can do this equation:-
8-7x = -29
First minus 8 from both sides then you are left with :-
-7x= -37 (because 8 minus 8 is 0. And -29 minus 8 = -37)
Then divide -7 from both sides because it is the inverse operation of multiplication.
Then after dividing you are left with
x= 5.29
