Question

Verify p – (– q ) = p + q , for p = 28 and q = 17
pls show calculation and steps

Answer 1

Answer:

Step-by-step explanation:

28-(-17)=28+17=45

28+17=45

Answer 2

Answer:

Given:          p = 28 and q = 17

To prove:      p – (– q ) = p + q

Proof:    First of all taking LHS,

                    =   p – (– q )

                    =  p + q

                    = 28 + 17

                    = 43

now,

Taking RHS,

                  = p + q

                  = 28 + 17

                  = 43

∴ So here LHS = RHS.

                                  hence proved.
