simplify

(10 a + 12 b - 3 c) - (7 a + 6 c - 9 d)

3 a + 12 b - 9 c + 9 d

Solution steps

(10 a + 12 b - 3 c) - (7 a + 6 c - 9 d)

Apply rule:

(a) = a

(10 a + 12 b - 3 c) = 10 a + 12 b - 3 c

= 10 a + 12 b - 3 c - (7 a + 6 c - 9 d)

Apply the distributive law:

- (a + b) = - a - b

- (7 a + 6 c - 9 d) = - 7 a - 6 c + 9 d

= 10 a + 12 b - 3 c - 7 a - 6 c + 9 d

Group like terms

= 10 a - 7 a + 12 b - 3 c - 6 c + 9 d

Add similar elements:
