Answer:
11
Step-by-step explanation:
When you have a positive number minus a negative number it will automatically turn into addition.
EX.
7-(-4) turns into 7+4
It’s 11 because you keep the 7 switch the minus sign to an addition sign and you also switch the negative 4 to a positive 4. This process is called keep, switch, flip and is only used if you are subtracting!
