Answer:

Answer 2

Answer:

hope that help

have a nice day

Step-by-step explanation:

-7 -(-5)

the above is known by the question

the new equation will be

-7 + 5

because we know that - - = +

the same  applies above

now ,

we will solve the new equation

-7+5 = -2

( how -2 ?

so ,

as we know - + = -

and the sign put is always of the bigger digit

here 7 is greater than 5 , so we have taken the sign of 7 instead of 5 )

2nd question is

2 - 7

that's kind of easy

lets do it

so we know that when there is no sign , its understood that the sign is of plus +  so here we know that its +2

moving ahead

+2 -7 = -5

( how -5 ?

so as we know that + - = -

and the and the sign put is always of the bigger digit

here 7 is greater than 2 , so we have taken the sign of 7 instead of 2 )

HOPE THAT HELP

HAVE A NICE DAY!
