Step 1.1.1

Apply the distributive property.

$0.5 (7 m) + 0.5 \cdot - 5 + 3 = 8 (2 m + 0.5)$

Step 1.1.2

Multiply $7$ by $0.5$ .

$3.5 m + 0.5 \cdot - 5 + 3 = 8 (2 m + 0.5)$

Step 1.1.3

Multiply $0.5$ by $- 5$ .

$3.5 m - 2.5 + 3 = 8 (2 m + 0.5)$

Step 1.2

Add $- 2.5$ and $3$ .

$3.5 m + 0.5 = 8 (2 m + 0.5)$
