Question

Please help me fast please

Answer 1

8+6+6-9=20-9=11

(-+-=+,,)

10+5-(-10)=15+10=25

9-6+4=9+6-8

3+4=15-8

7=7

true

Answer 2

Step-by-step explanation:

1. 8-(-6)+6-(9)

= 8+6+6-9

= 11

2. Sum of 10 and 5 = 10+5 = 15

Now we will subtract -10 from this sum,

15-(-10)

=15+10

= 25

3.First we will solve the left side,

9+(-6)-(-4)

= 9-6+4

= 7

No we will solve the right side,

9-(-6)-8

= 9+6-8

= 7

On comparing the two answers we get that,

7=7

Therefore, Left side = Right side

Hence, it is true.
