Question

this plz answer guys ​

Answer 1

Answer:

-6=-6

Step-by-step explanation:

You can solve by -

[ 7+(-8)]+(-5) = 7+[(-8)+(-5)]

[-1]-5 = 7+[-13]

which implies -6 = -6

Answer 2

☞ [7 + (-8)] + (-5) = 7 + [(-8) + (-5)]

∴ RHS = LHS

∴ LHS = 7 + [(-8) + (-5)]

= 7 + (-8 - 5)

= 7 + (-13)

= 7 - 13

= (-6)

∴ LHS = (-6) = RHS = [7 + (-8)] + (-5) = (-6)

☞ Hence, [7 + (-8)] + (-5) = 7 + [(-8) + (-5)]
