Which property of equality would you use in the first step of solving this equation 2x-6=12

1. Add 6 on both sides, under 6 and under 12

2. 6 cancels out

3. Add 12 and 6 to get 18

4. Bring down 2x equal to 18 and divide by 2

5. 2 cancels out

6. 18 divided by 2 equals 9

7. X=9

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!
