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
