pls mark me as brainliest plzzzzzzzzzzzzzzzzz yaar

can u please mark me as brainliest

Answer 2

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: SOLUTION \: \: } \mid}}}}}$

$\: \: \: \: \: \: \: \: \tt{3(x + 2) - 2(x - 1) = 7} \\ \\ \tt{\Longrightarrow \:3x + 6 - 2x + 2 = 7 } \\ \\ \tt{\Longrightarrow \: 3x - 2x = 7 - 6 - 2} \\ \\ \tt{\Longrightarrow \: x = 7 - 8} \\ \\ \: \: \: \: \: \: \: \tt{\therefore \: x = - 1}$

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: VERIFICATION \: \: } \mid}}}}}$

$\tt{L.H.S. =3(x + 2) - 2(x - 1) } \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{ = 3 \{( - 1) + 2 \} - 2 \{( - 1) - 1 \}} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{ = 3( - 1 + 2) - 2( - 1 - 1)} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{ = 3 \times 1 - 2 \times ( - 2)} \\ \\\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{ = 3 + 4} \\ \\\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \tt{ = 7 = R.H.S. } \\ \\ \\ \: \: \: \: \: \therefore \: \underline{ \tt{ \: \: L.H.S. = R.H.S. \: \: }} \:$
