Answer 2

Step-by-step explanation:

let the number be X

the first number is (-3/5)

result is -2

so

the equation is

X+(-3/5)=(-2)

OPEN THE BRACKET SO WE HAVE TO TAKE HELP OF RULE (+)×(-)=(-)

SO

X-3/5=(-2)

IN LHS 5 IS DIVIDING IF WE CHANGE THE SIDE IT WILL MULTIPLY

X-3=(-2)×5

X-3=(-10)

X=(-10)+3

+3 BECAUSE WE ARE USING THE RULE OF CHANGING SIDE

IF WE CHANGE THE SIDE (+) WILL BECAME (-) AND (-) WILL BECAME (+)

SO

X=-7
