2-50.

Solve each of the following equations.

$2 x + 8 = 3 x - 4$

Steps (a):
$2x+8=3x−4$
$−2x\ \ \ \ −2x$
$8=x−4$

$8=x−4$
$+4\ \ \ \ +4$
$12=x$

$1.5 w + 3 = 3 + 2 w$

Answer (b):
See part (a).
$w=0$

$48 + 8 x + 23 = 7$

Hint (c):
First, combine like terms, then see part (a).

$6 x - 21 = 5 x + 17 + x$

Steps (d):
$6x−21=6x+17$
$−6x\ \ \ \ \ \ −6x$
$−21=17$
Is this a possible solution?
