expand-2(1-6r=82)

expand

- 2 (1 - 6 r = 82)

- 2 + 12 r = 82

Solution steps

- 2 (1 - 6 r = 82)

= - 2 (1 - 6 \cdot 82 = r)

Apply the distributive law:

a (b - c) = ab - a c

a = - 2, b = 1, c = 6 r = 82

- 2 \cdot 1 - (- 2) \cdot 6 r = 82

Apply minus-plus rules

- (- a) = a

- 2 \cdot 1 + 2 \cdot 6 r = 82

Expand

- 2 \cdot 1 + 2 \cdot 6 r : - 2 + 12 r

- 2 + 12 r = 82
