See the attached picture:
Given equation: 3 + x/2 = 10
1st step subtract 3 from each side:
x/2 = 7
2nd step multiply both sides by 2:
x = 14
Step 1)
3 + x/2 = 10 ..............This is given
Step 2)
x/2 = 7 ....................... Multiplication property of equality.
This step is wrong. This step is called "Subtraction property of equality ". This means you have to subtract 3 from both sides
3 + x/2 - 3 = 10 - 3
Simplifying
x/ 2 = 7
Step 3)
x = 14 ....This is called "Multiplication property of equality " because you multiply both sides by 2.
Hope that helps.

First you add 76 to get
-4x<24
And Then you divide by -4 and sincr its a negative you flip the sign to get
x>-6
That might be wrong Idk
0.4 x >= 327 Divide by 0.4 x >= 327/0.4 which is not going to be an even number. x >= 817. 5 puppies. So they need to sell 0.5 more puppies. Better round this quickly before someone decides to do something stupid to get the extra 1/2 puppy. For us it's simple. Just add a 1/2 puppy more. x >= 818 puppies <<<<==== answer.
The common difference is 1 1/3 40-1 1/3= 38 2/3 38 2/3-1 1/3=37 1/3 37 1/3-1 1/3=36 Therefore the missing number is 38 2/3
