5(x-7)=29
5x-35=29
+35 +35
5x=64
x=64/5
x=12.8
First you use the distrubutive property and get 5x-35=29. Then add the 35 to 29 and get 64. To get the x by itself, divide by five and you get 12.8.

5(x- 7)=29
first times everything in () by 5
5x- 35 = 29
Then add 35 to both sides
5x - 35 = 29
+ 35 = + 35
5x = 64
Divide by 5
5x = 64
---------
5
x = 12.8
check
5(12.8 - 7) = 29
64- 35 = 29
29 = 29
(YAY)
Answer is X = 12.8

5(x-7)=29 - Original equation
5x-35=29 - Distributive Property
5x=64 - Add 35 to both sides
x=64/5=12.8 - Divide both sides by 5

x= 12.8 because 5(x-7)=29. then you do the opposite of it to find the answer because that is the solution. like first you divide 29 by 5 because you do the opposite to the answer(which is 29). then you have x-7= 5.8 because 29 divided by s is 5.8.then you add 7 to 5.8 which is 12.8. so x=12.8.

x=12.8
first multiply 5 and x, then multiply 5 and 7 and you should no the rest.
sub. 12.8 for x and you'll get 29.
5(x-7) becomes (5(12.8)-35)=29

5(x-7) = 29
Expand it...
5x - 35 = 29
Get rid of the 35..
5x -35 + 35 = 29 + 35 (what you do to one side of the equation, you must do to the other)
5x = 64
x = 64/5
Are you sure your question is correct, usually they make it easy so that X ends up being a whole number.
To check
5 (x-7) = 29
5( 64/5 -7) = 29
64 - 35 = 29
29 = 29
Check complete.

5(x-7)=29
Change the left side to 5x+5*-7
So 5x+5*-7=29
5x+-35=29
Add 35 to each side because since you are adding -35 add 35 to 29 which equals 64
5x=64
Divide by five on each side.
x=12.8

5(x-7)=29
[5(x-7)]/5=29/5 first divide both sides by 5
x-7=5.8 simplify to get x-7=5.8
x-7+7=5.8+7 now add 7 to both sides
x=12.8 simplify and you get x=12.8
x is 12.8 because after solving it by using inverse operations and by isolating the variable, you get 12.8.
