First bracket expanded :

9 x 3x = 18x
9 x 7 = 63

Second bracket expanded :

-4 x 6x = -24x
-4 x 7 = -28

Taking the brackets away from each other :

18x -24x = -6 x
63 - 28 = 35
35 - 1 = 34

The answer is

-6x + 34

Answer: 3x+34

Step-by-step explanation:

9(3x+7)-4(6x + 7)- 1

27x+63−4(6x+7)−1

27x+63−(24x+28)−1

27x+63−24x−28−1

(27x−24x)+(63−28−1)

3x+34
