part one of this would be x=6;

2x6 is 30

30+5 is 35

part two of this would be x=20;

20x4 is 80

80-7 is 73

Answer:

x = 15 and x = 20

Step-by-step explanation:

(2)

35 = 2x + 5 ( subtract 5 from both sides )

30 = 2x ( divide both sides by 2 )

15 = x

(3)

4x - 7 = 73 ( add 7 to both sides )

4x = 80 ( divide both sides by 4 )

x = 20
