​

Answer 1

$\large \underline { \underline{ \green{ \bf Given :}}}$

• 4x + 2y = 5

• 2x + 2y = 3

$\large \underline { \underline{ \green{ \bf To \: Find :}}}$

• Value of x

$\large \underline { \underline{ \green{ \bf Solution:}}}$

$\: \: \: \: \: \: \sf 4x +\cancel{ 2y} = 5 \\ \: \: \: \: \: \: \sf 2x +\cancel{ 2y} = 3 \\ \: \: \: \underline{ \ - \: \: \: \: \: \: \: - \: \: \: \: \: \: \: \: - } \\ \: \: \: \: \: \: \sf2x = 2 \\ \\ \implies \sf x = \frac{2}{2} \\ \\ \Large \implies \boxed{ \sf \purple{x = 1}}$
