Answer:

ito na po ang kaisa isang formula

Answer:

1. - 24
2. 3
3. -35
4. -13
5. -36
6. There is no solution for 5+=2

Step-by-step explanation:

1. Use the rule a-b = - (b-a) let's use algorithm method 72- 48 =24 so we now have - (72-48) therefore; 48 - 72 = - 24
2. We'll just remove the parenthesis so the equation will become - 12-15 so by using subtraction operation the answer will be 3
3. Use the rule - a-b = - (b+ a) we will have - (17 +18) let's use the addition operation for - 17-18 and the result will be 35. Copy the sign of the bigger number so the correct answer will be - 35
4. Let's simplify - 1-8-4 results to - 9-4. Perform the addition operation and copy the sign of the bigger number so - 9 - 4 = - 13
5. Simplify - 4-20-12 is equal to - 24 - 12. Add the numbers and copy the sign of the bigger number so the answer will be - 36
