Answer 1

Step-by-step explanation:

$\bold{Given -} \\ \huge{ \circ + \triangle} = 8 \: \small{ ......(a)} \\ \huge { \circ - \triangle} = 4 \: \small{ ......(b)}\\ \huge{ \star + \square } = 12 \: \small{ ......(c)}\\ \huge { \star - \square } = \square \: \small{ ......(d)}\\ \huge{\square + \square} = \star\small{ ......(e)} \\ \\ \bold{To \: find - } \\ Value \: of \: \star , \: \circ , \: \square , \: and \: \triangle$

$\bold{Now, } \\ Adding \: \bold{(a)} \: and \: \bold{(b)} \\ \\ \huge{ \circ + \cancel{\triangle} = 8} \\ \huge{ \circ - \cancel{\triangle} = 4} \\ \underline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: } \\ \huge{2 \circ} = 12 \\ { \circ} = \cancel{ \frac{12}{2} } \\ \huge \circ = 6 \\ \\ \bold{Now,} \\ Substituting \: the \: value \: of \: \circ \: on \: (a) \\ \huge{ \circ + \triangle = 8} \\ 6 + \triangle = 8 \\ \triangle = 8 - 6 \\ \huge{\triangle = 2}$

$\bold{Now,} \\ \huge{\square + \square = \star} \\ \huge{2 \square = \star} \\ \huge{ \square = \frac{ \star}{2} } \\ \\ \bold{Now,} \\ Substituting \: the \: value \: of \: \square \: on \: (c) \\ \\ \huge{ \star + \square = 12} \\ \huge{ \star + \frac{ \star}{2} } = 12 \\ \frac{2 \star + \star}{2} = 12 \\ \frac{ 3\star}{2} = 12 \\ 3 \star = 24 \\ \star = \cancel{\frac{24}{3} } \\ \huge{ \star = 8} \\ \\ \bold{Now,} \\ Substituting \: the \: value \: of \: \star \: on \\ \square = \frac{ \star}{2} \\ \square = \cancel{\frac{8}{2} } \\ \huge{ \square = 4}$

$Hence, \\ The \: value \: of \\ \huge{\star =8 } \\ \huge{ \square = 4} \\ \huge{ \triangle = 2} \\ \huge{ \circ = 6}$
