2-72.

Solve each of the following equations. Homework Help ✎

1. $2 x + 8 = 3 x - 4$

• 2x + 8 = 3x − 4
−2x −2x
8 = x − 4
8 = x −4
+4 +4
12 = x

1. $1.5 w + 3 = 3 + 2 w$

• See part (a).
w = 0

1. $48+8x+23=7$

• First, combine like terms, then see part (a).

1. $6 x - 21 = 5 x + 17 + x$

• 6x −21 = 6x +17
−6x −6x
−21 = 17
Is this a possible solution?
