Question

8+(-7)-(-4)=8+7-4 is it true or false

Answer 1

The equation is false

Given:

$8+(-7)-(-4)=8+7-4$

We take LHS of the above equation,

$8+(-7)-(-4)=8-7+4$

                         $=1+4$

                         $=5$

Now we write RHS of the above equation,

         $8+7-4=15-4$

                        $=11$

LHS and RHS are not equal.

Hence, given equation is false

Answer 2

Given ; 8+(-7)-(-4)=8+7-4

To Find ; To verify whether the statement is true or false

Solution ; 8+(-7)-(-4)=8+7-4

In verifying these statements we first need to solve both the sides and then check LHS = RHS

First solve LHS

8+(-7)-(-4)

8 -7 + 4

12 - 7

5

Solving RHS

8 +7 -4

15 - 4

11

LHS is not equal to RHS

Hence the given statement is false
