expand-2.5(-3+4n=8)

expand

- 2.5 (- 3 + 4 n = 8)

7.5 - 10 n = 8

Solution steps

- 2.5 (- 3 + 4 n = 8)

= - 2.5 (- 3 + 4 \cdot 8 = n)

Apply the distributive law:

a (b + c) = ab + a c

a = - 2.5, b = - 3, c = 4 n = 8

- 2.5 (- 3) + (- 2.5) \cdot 4 n = 8

Apply minus-plus rules

- (- a) = a, + (- a) = - a

3 \cdot 2.5 - 4 \cdot 2.5 n = 8

Expand

3 \cdot 2.5 - 4 \cdot 2.5 n : 7.5 - 10 n

7.5 - 10 n = 8
