3 (x + 7) - 4 =7x-1 please solve it don't spam

Answer»

$: \implies \: 3(x + 7) - 4 = 7x - 1$

$: \implies \: 3x + 21 - 4 = 7x + 1$

$: \implies \: 21 - 4 + 1 = 4x$

$: \implies18 = 4x$

$: \implies \: x = \frac{18}{4}$

$\therefore { \: \: x = \frac{9}{2}}$

$\therefore \: \: \: \: \fbox{x = 4.5}$
