Answer:

x=-1  (1)

Step-by-step explanation:

you need to use distributive property, 2 times 3x equals 6x, 2 times 5 equals 10. 3 times 2x equals 6x,  3 times 3 equals 9.

6x-10+6x+9

what you do to one side you need to do to both so-10 + 10 equals 0 then 9 minus 10 equals -1. 6 minus 6 equals 0, 6 - 6 0 again.

x=-1  (1)
