Question

find the value of x if x/4 + 2/5 = x /2 - 1​

Answer 1

Answer:

based on BODMAS

X=(4/5)-2/1/4×2

X=(4/5)-2/1/2

X=(4/5)-2×2

X=(4/5)-4=4-20/5=-16/5

X-1=-16/5-1=-16-5/5=-21/5=-4.2

$\bf \: \: find \: x \: if :$

$\rm \bf \frac{x}{4} + \frac{2}{5} = \frac{x}{2} - 1$

${\color{maroon}\large\mathcal{ANSWER}}$

$\mapsto \rm \frac{x}{4} + \frac{2}{5} = \frac{x}{2} - 1$

$\mapsto \rm \frac{x}{4} - \frac{x}{2} \ = - 1-\frac{2}{5}$

$\mapsto \rm \frac{x}{4} - \frac{x}{2} \ = - 1-\frac{2}{5}$

$\mapsto \rm \frac{x-2x}{4} = - 1-\frac{2}{5}$

$\mapsto \rm \frac{x-2x}{4} = \frac{-5-2}{5}$

$\mapsto \rm \frac{x-2x}{4} = \frac{-7}{5}$

$\mapsto \rm {x-2x}= 4(\frac{-7}{5})$

$\mapsto \rm {x-2x}= \frac{-28}{5}$

$\mapsto \rm {-x}= \frac{-28}{5}$

$\mapsto \rm {\cancel-x}= \frac{\cancel-28}{5}$

${\boxed{\color{navy} \mapsto \rm {x}= \frac{28}{5}}}$
