Simplify:

6 9x-2+3x-5

57 x + - 7

Step-by-step explanation:

Simplify the following:

6 9 x + 3 x - 5 - 2

6*9 = 54:

54 x + 3 x - 5 - 2

Grouping like terms, 54 x + 3 x - 5 - 2 = (54 x + 3 x) + (-2 - 5):

(54 x + 3 x) + (-2 - 5)

54 x + 3 x = 57 x:

57 x + (-2 - 5)

-2 - 5 = - 7:

Answer: 57 x + - 7
