Answer:
6
Explanation:
1. 4+2x=16
2. 4- 4+2x=16 -4
3. 2x=12
4. 2\ 2x=12 /2
5. x=6
16 is the total and you add the group of 4 and the two groups with x amount. then subtract 4 from 4 and 16, and you get 2x=12. Then divide 2 from 2x and 12, ( you are dividing 2 from 2x in order to have x alone). Then in the end you get x=6. Hope this helped<3
