Answer:
what grade level
Step-by-step explanation:
f) 16 - p = 12 minus 12
4 - p = 0 plus p
p = 4
g) 18 - 2p = 6 divide by -2
-9 + p = -3 plus 9
p = 6
h) p x 2 + 4 = 9 divided by 2
p + 2 = 4.5 minus 2
p = 2.5
i) p x 4 - 3 = 1 plus 3
p x 4 = 4 divided by 4
p = 1
No Its not Rational Number
-4/3 should be the answer
There is no b unfortunately
Find inverse of x+a
interchAnge
Inverse is
Now
- x-a=cx-d
- x-cx=a-d
- x(1-c)=a-d
- x=a-d/1-c
So
You can have any number according to this but
- c must not be 1
- a and d must not be equal .
- All three should belongs to integers set
Note:-
As there is no b given in question (May be missed in typing) Part-2 's equation can't be executed and part 3 also
