Answer:
FGCE
Step-by-step explanation:
1. 3x - 9 = 30
add 9 to 30 ( 30 + 9 = 39) divide 39 by 3 (39 ÷ 3 = 13)
2. x/5 + 4 = 6
subtract 4 from 6 (6 - 4 = 2) multiply 2 by 5 (2 x 5 = 10)
3. x/2 + 6.5 = 8
subtract 6.5 from 8 (8 - 6.5 = 1.5) multiply 2 by 1.5 (2 x 1.5 = 3)
4. -2x + 2 = 18
subtract 2 from 18 (18 - 2 = 16) divide -2 from 16 (16 ÷ -2 = -8)
