$x = -2$

Use the distributive law to multiply out the brackets first so we have separate terms.

$3 - 5(x + 2) = 3(x + 1) + 6$

$3-5x-10 = 3x +3+6$

$cancel3-5x-10 = 3x +cancel3+6$

$-10-6 = 3x+5x " x terms on right to keep them positive"$
$-16 = 8x$

$x = -2$

How do you solve 3 - 5(x + 2) = 3(x + 1) + 63 - 5(x + 2) = 3(x + 1) + 6?
