Answer 2

Hi , for the second one the answer is 25
x - [-24] equals 49
We have to  change the subtraction sign to an addition sign and the number -24 to its opposite .
25+24 equals 49
For the third one the answer is -25 because 3 plus -25 equals to -22.
For the fourth one the answer is 26
we change the sign to an addition sign and the number 26 to its opposite , the we just add .
