Hi again!
Come on, you got this!
2x + 6 - 6x =30
All you have to do is put the ones alike together
2x - 6x + 6 = 30
-4x + 6 = 30
Transfer 6 to the right side(don't forget to change the sign)
-4x = 30 - 6
-4x = 24
x = 24/-4
x = -6
The correct answer is option A

Answer:
y= 12
Step-by-step explanation:
2/3 y + 7 = 15
Subtract 7 from each side
2/3 y + 7-7 = 15-7
2/3 y = 8
Multiply each side by 3/2 to isolate y
3/2 * 2/3 y = 3/2 * 8
3/2 * 2/3 y = 3 * 4
y = 12
