Question

Q22 .3x +4/2-6x=-2/5 find the value of x.
A) 9 B ) -8
c) 7 d -6​

Answer 1

Answer:

$3x + \frac{4}{2} - 6x = \frac{ - 2}{5}$

$- 3x + \frac{4}{2} = \frac{ - 2}{5}$

$- 3x = \frac{ - 2}{5} - \frac{4}{2}$

$- 3x = \frac{ - 4 - 9}{10}$

$- 3x = \frac{ - 13}{10}$

$transporting$

$x = \frac{ - 13}{10} \div - 3$

$reciprocal \: of \: - 3 \: is = \frac{ - 1}{3}$

$x = \frac{ - 13}{10} \times \frac{ - 1}{3}$

$x = \frac{13}{30}$
