Answer:
Step-by-step explanation:
Here is the workings
2x+4y+6+2y-5+3x combine like terms
2x+3x+4y+2y+6-5
Step 2
2x+3x+4y+2y+6-5 Add the similar exponents
5x+4y+2y+6-5
5x+6y+6-5
Step 3
5x+6y+6-5 Add and subtract
Your answer would be 5x+6y+1
Let the number be x.
x/3 + 12 = 46
Subtract 12 from both sides and you will get:
x/3 = 34
Multiply both sides by 3:
x = 102
There are so many relationships between the original entity and new relation.
The relation mapped from an entity involved in a 1:1 unary relationship contains a foreign key that correspond to its own primary key. 1 to one foreign key will be unique.
What do u mean like 82+82?
Well, 10x4=40 because 10+10+10+10=40 and that means your answer must be 40 ones or you asked something else.
