Question

$\frac{3}{4}(7x - 1) - ( 2 \times - \frac{1 - x}{2}) = x + \frac{3}{2}$
please help karo i will mark as the brainliest​

Answer 1

As i understand ur question....

$\frac{3}{4}(7x - 1) - ( 2 - \frac{1 - x}{2}) = x + \frac{3}{2} \\ </strong><strong>=</strong><strong>></strong><strong> \frac{21x}{4} - \frac{3}{4} - 2 + \frac{1}{2} - \frac{x}{2} = x + \frac{3}{2} \\ </strong><strong>=</strong><strong>></strong><strong> \frac{21x}{4} - \frac{x}{2} - x = \frac{3}{2} - \frac{3}{4} + 2 - \frac{1}{2} \\ \\</strong><strong>=</strong><strong>></strong><strong> \frac{21x - 2x - 4x}{4} = \frac{6 - 3 + 8 - 2}{4} \\ \\</strong><strong>=</strong><strong>></strong><strong> \frac{15x}{4} = \frac{9}{4} \\</strong><strong>=</strong><strong>></strong><strong> 15x = 9 \\</strong><strong>=</strong><strong>></strong><strong> x = \frac{9}{15} \\ </strong><strong>=</strong><strong>></strong><strong>x = \frac{3}{5}$

Hello mate i think u will get it..
