Answer:

x -7y

Step-by-step explanation:

7x - 9y - 6x + 2y

Rearrange so like terms are together (these are terms that are similar such as 5b and 7b; 7 and 1)

7x - 6x - 9y + 2y

Group into brackets one-by-one and solve

(7x-6x) -9y + 2y

x -9y + 2y

x (-9y + 2y)

x -7y

Note that 1x, 1b, 1z etc are simply written as their variable eg x, b and z
