Questions

1. 47 + __ = 103 x 75 - 4367 = ____ .
2. 85 + 35 - 9 x 825 + 8 - 93 =_____.

Solution 1

• $\sf{47 + \underline{ \: \: \: \: \: \bf{x} \: \: \: \: \: } = 103 \times 75 - 4367 = \underline{ \: \: \: \: \: \bf{y} \: \: \: \: \: } .}$

For x

${ \: \: \: \implies \: \sf \: \: 47 + x = 103 \times 75 - 4367}$

${ \: \: \: \implies \: \sf \: \: 47 + x = 7725 - 4367}$

${ \: \: \: \implies \: \sf \: \: x = 3358 - 47}$

${ \: \: \: \implies \: \bf \: \: x = 3311}$

For y

${ \: \: \: \implies \: \sf \: \: 103 \times 75 - 4367 = y}$

${ \: \: \: \implies \: \sf \: \: 7725 - 4367 = y}$

${ \: \: \: \implies \: \bf \: \: y = 3358}$

$\gray{\sf{47 + \underline{ \: \: \: \: \: \bf{3311} \: \: \: \: \: } = 103 \times 75 - 4367 = \underline{ \: \: \: \: \: \bf{3358} \: \: \: \: \: } .}}$

Solution 2

$\sf{ \: \: \: \mapsto \: \: 85 + 35 - 9 \times 825 + 8 - 93 }$

$\sf{ \: \: \: \mapsto \: \: 85 + 35 - 7425 + 8 - 93 }$

$\sf{ \: \: \: \mapsto \: \: 128 - 7518 }$

$\sf{ \: \: \: \mapsto \: \: 7646 }$

${ \sf\therefore \gray{ \: \: 85 + 35 - 9 \times 825 + 8 - 93 \bf = 7646}}$
