Question

x if 9 - 5 7 by 8 = 2 x minus 1 by 8​

Answer 1

$9 - 57 \div 8 = 2x - \frac{1}{8} \\ - 48 \div 8 = 2x - \frac{1}{8} \\ - 6 = 2x - \frac{1}{8} \\ - 6 + \frac{1}{8} = 2x \\ \frac{ - 48 + 1}{8} = 2x \\ \frac{ - 47}{8 \times 2} = x \\ \frac{ - 47}{16} = x$

Answer 2

$\red{ \huge{ \underline{ \overline{ \mid{ \bold{ \: \:QUESTION\: \: \mid}}}}}}$

$\huge{\bold{Find \: \: \: x \: \: ,\: \: If}}$

$\huge{ \bold{9 - \frac{57}{8} = 2x - \frac{1}{8} }}$



$\red{ \huge{ \underline{ \overline{ \mid{ \bold{ \: \: SOLUTION \: \: \mid}}}}}}$



$\huge{ \bold{9 - \frac{57}{8} = 2x - \frac{1}{8} }} \\ \\ \\ \huge{ \bold{ = > 2x - \frac{1}{8} = 9 - \frac{57}{8} }} \\ \\ \\ \huge{ \bold{ = > 2x - \frac{1}{8} = \frac{72 - 57}{8} }} \\ \\ \\ \huge{ \bold{ = > 2x - \frac{1}{8} = \frac{15}{8} }} \\ \\ \\ \huge{ \bold{ = > 2x = \frac{15}{8} + \frac{1}{8} }} \\ \\ \\ \huge{ \bold{ = >2x = \frac{15 + 1}{8} }} \\ \\ \\ \huge{ \bold{ = > 2x = \frac{16}{8} }} \\ \\ \\ \huge{ \bold{ = > 2x = 2}} \\ \\ \\ \huge{ \bold{ = > x = \frac{2}{2} }} \\ \\ \\ \huge = > {\boxed { \bold{ \: \: \: \: x = 1 \: \: \: \: }}}$



$\red{ \huge{ \underline{ \overline{ \mid{ \bold{ \: \: VERIFICATION \: \: \mid}}}}}}$



$\underline{ \huge{ \bold{ \: \: \: x = 1 \: \: }}} \\ \\ \\ \huge{ \bold{L.H.S. = 9 - \frac{57}{8} }} \\ \\ \huge{ \bold{ \: \: \: \: \: \: \: \: = \frac{72 - 57}{8} }} \\ \\ \\ \huge{ \bold{ \: \: \: \: \: \: \: \: \: = \frac{15}{8} }}$



$\huge{ \bold{R.H.S. = 2x - \frac{1}{8} }} \\ \\ \\ \huge{ \bold{ \: \: \: \: \: \: \: \: = 2 \times (1) - \frac{1}{8} }} \\ \\ \\ \huge{ \bold{ \: \: \: \: \: \: \: \: = 2- \frac{1}{8} }} \\ \\ \\ \huge{ \bold{ \: \: \: \: \: \: \: \: = \frac{16 - 1}{8} }} \\ \\ \\ \huge{ \bold{ \: \: \: \: \: \: \: \: = \frac{15}{8} }} \\ \\ \\ \huge{ \bold{ \: \: \: \: \: \: \: \: = L.H.S.}}$

$\huge{ \bold{So,}} \\ \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \underline{ \huge{ \bold{ \: \: L.H.S. = R.H.S.\: \: }}}$
