Given :

  • (– 4) + [15 + (–3)] = [– 4 + 15] + __

To find :

  • We have to find the value of the missing Integer

Solution :

To find the missing Integer we have to first solve step by step as according to the brackets first this one "[ ]" and after it we will solve small one "( )"  So, then we take RHS to LHS so it will become "  - " and then, we can find the value of "x" So, let's solve!

:  \implies  \sf Let \: the \: missing \: integer \: be \: x \\  \\  \\ :   \implies \sf (- 4) + [15 + (-3)] = [- 4 + 15]  +  \sf \purple{(x)} \\  \\  \\  \:  \:  \:  \:  \:  \:  :  \implies \sf (- 4) + [15  \: -  \: 3)] = [- 4 + 15] +  \sf \purple{(x)} \\  \\  \\  :  \implies \sf (-4) + [12] = [11] +  \sf \purple{(x)} \\  \\  \\  :  \implies \sf 8 = 11 +  \sf \purple{(x)} \\  \\  \\   \therefore  {\sf{ \underline{Now \: we \: will \: send  \: 11 \: from\: RHS\: to \: LHS \: so \: it \: will \: become \:  - 11}}} \\  \\  \\  :  \implies \sf 8 - 11 \:  =  \sf \purple{(x)}  \\  \\  \\  \:  \:  \:  \: :  \implies { \underline{ \boxed{ \pink{ \mathfrak{x \: \leadsto \:  - 3}}}}}  \\  \\  \\   {\dag \:  {\sf { \underline{Verification}}}} \\  \\  \\  :  \implies  \sf\: (- 4) + [15 + (-3)] = [- 4 + 15]  +  (- 3) \\  \\  \\   \:  \:  \: :   \implies \sf (- 4) + [15  \: - \: 3)] = [- 4 + 15] + ( - 3) \\  \\  \\  :  \implies \sf (-4) + [12] = [11] +  ( - 3)  \\  \\  \\   :  \implies  \sf\: 8 \:  = [11 - 3] \\  \\  \\  :  \implies \sf 8 = 8 \\  \\  \\    \leadsto {\pink{\bf{(- 4) + [15 + (-3)] = [- 4 + 15] +{ \blue{ \boxed {-3}}}}}}

•°• Hence, verified! that the value of the missing Integer is -3
