In integers subtraction and addition are almost same ....
Addition<span> :in addition if both numbers have different signs ..i.e - and + then we would find the difference and put the greater number sign ...For eg:(-6) + 12 =6 ...</span>
<span> if both are same ..i.e if both are either positive(+) or negative(-) then you add(or find the sum) and put the common sign ... For eg :+5+10 = +15 and (-5) + (-10) = (-5)]
Subtraction: in subtraction what you do is changing the sign of the second number ...and then depending upon the both signs follow the rules of addition ...
for eg: 6 - 4 ..it becomes 6 + (-4) ...so as they have different signs we can subtract them and put the greater number sign ...
i.e, 6 + (-4) = 2 ...
To find the sum follow these rules ......mentioned above ....
u can ask if you have any doubt ....
Hope it helps !!!</span>
Move 2a to the other side, making it negative
32=6a-2a
32=4a
divide both sides by 4
8=a
180° angle is a straight line

Answer:
GCF = 4xy⁷z
Step-by-step explanation:
Do Prime Factorizations for each term and select only those terms common to each:
28xy⁹z = 2·2·7·x·y·y·y·y·y·y·y·y·y·z
32x²y⁷z = 2·2·2·2·2·x·x·y·y·y·y·y·y·y·z
GCF = 2·2·x·y·y·y·y·y·y·y·z
GCF = 4xy⁷z
So with the 2/3 you factor out the 3 from the expression by multiplying 3, which cancels out the bottom number 3 and leaves you with 2(-3m+4). You then distribute 2 through the parenthesis which gives you the answer -6m+8 <span />
