Answer:
7 - - 5 = 12
Step-by-step explanation:
(5 + 7x + 6)/2 = 3x + 9
7x + 11 = 6x + 18
7x - 6x = 7
x = 7
EF = 3x + 9
= 3(7) + 9
= 21 + 9
= 30
Answer:
y = 7, x = 7
Step-by-step explanation:
11y + 13 = 90
11y = (90 - 13)
11y = 77
y = 7
2x + 6 = 20 (because 20 is half of 40)
2x = (20 - 6)
2x = 14
x=7
