Answer:
hello!!!
We will learn it simple method,we know that multiplication of whole numbers is repeated addition. For example
3*4= 4+4+4
in this same way we can say that
[-12]=(-3)+(-3)+(-3)+(-3)
also,
4(*-3)=(-12)
for the second equation we can take it same as the above one
So it make no diffrence when we multiplied integers as (positive)*(negative) OR (NEGATIVE)*(POSITIVE)
And so now we can say
FOR ANY TWO POSITIVE INTEGER a and b WE CAN SAY
(-a) *(b) = (-b)*(a) = -(a*b)
HOPE FULLY U MAY LIKED MY ANSWER GIVE POSITIVE FEEDBACK AND IF WANTS ANYTHING OTHER YOU MAY ASK ME IN COMMENT

Step-by-step explanation:
Sum of a number p and seven (p+7) is divide by 12 ((p+7)/12)
the result (=) 3 (3)
(p+7)/12=3
multiply both sdies by 12 to clear fraction
p+7 times 12/12=3 times 12
p+7=36
subtract 7 from both sides
p+7-7=36-7
p=29
the number is 29
