Question

Solve for x 4(3+x)+x=x+4 TYYY

Answer 1

Answer:

$4(3 + x) + x = x + 4$

$12 + 4x + x = x + 4$

$12 + 5x = x + 4$

$5x - x = 4 - 12$

$4x = - 8$

$\large \: x = \frac{ - 8}{4}$

$x = - 2$

Answer 2

$\sf\longmapsto 5x + 12 = x + 4$

$\sf\longmapsto 5x + 12 - 12 = x + 4 - 12$

$\sf\longmapsto 5x = x + 4 - 12$

$\sf\longmapsto 5x = 4 - 12$

$\sf\longmapsto 5x = - 8$

$\sf\longmapsto( 5x - x)$

$\sf\longmapsto 4x = - 8$

$\sf\longmapsto \frac{ - 8}{4} = - 2$
