answer is -6

Step-by-step explanation:

rule 1

if both numbers carry same sign then just add it and put the sign of the numbers at front

ie. 3+7=10

-3-7=-10

rule 2

if opposite sign then subtract it and then put the sign of larger number

ie. 3+ (-7)= -4

consider example , 3 are -7 are oppositely charged numbers .so subtract it ,then it results 4 .put the sign of greater number 7>3 so 4 prefixxed by -.

so answer is -4

in your question ,

+3 an -9 are different signed numbers so subtract it .results 6 and 9>3 so 6 prefixxed by -

(sign of 9 in the expression)

so answer is -6
