simplify (7x-9y+14z)-(4x-2y-6z)

simplify

(7 x - 9 y + 14 z) - (4 x - 2 y - 6 z)

3 x - 7 y + 20 z

Solution steps

(7 x - 9 y + 14 z) - (4 x - 2 y - 6 z)

Apply rule:

(a) = a

(7 x - 9 y + 14 z) = 7 x - 9 y + 14 z

= 7 x - 9 y + 14 z - (4 x - 2 y - 6 z)

Apply the distributive law:

- (a - b) = - a + b

- (4 x - 2 y - 6 z) = - 4 x + 2 y + 6 z

= 7 x - 9 y + 14 z - 4 x + 2 y + 6 z
