Step 1.1

Apply the distributive property.

$3 r + 3 \cdot - 10 - 4 (7 t + 2 r)$

Step 1.2

Multiply $3$ by $- 10$ .

$3 r - 30 - 4 (7 t + 2 r)$

Step 1.3

Apply the distributive property.

$3 r - 30 - 4 (7 t) - 4 (2 r)$

Step 1.4

Multiply $7$ by $- 4$ .

$3 r - 30 - 28 t - 4 (2 r)$

Step 1.5

Multiply $2$ by $- 4$ .

$3 r - 30 - 28 t - 8 r$

$3 r - 30 - 28 t - 8 r$

Step 2

Simplify by adding terms.
