two step equations
4X + 32 = 72
X = 10
6X - 80 = 15X + 73
X = -17
456 = 8(X + 15)
X = 7
-8 = (8X + 16)/6
X = -8
Write an equation and solve:
Nancy sold half of her comic books and then bought 8 more. She now has 12. How many did she begin with?
X/2 + 8 =12
X = 8
26 + 11X = 158
X = 12
- 59 + 13X = 8X + 121
X = 36
642 = - 6(- 9X - 8)
X = 11
(5X + 6)/ - 6 = -6
X = 6
On Monday, 376 students went on a field trip. All 7 buses were filled and 5 students rode in cars. How many students were in each bus?
7X + 5 = 376
X = 53
- 30 - 11X = - 118
X = 8
- 2X - 200 = - 12X + 70
X = 27
8(7X + 7)= 560
X = 9
(6X + 3)/11 = 3
X = 5
Sam bought 6 new baseball cards. The next day his dog ate half of his collection. He now only has 34 cards left. How many cards did Sam start with?
(X + 6)/2 = 34
X = 62
21 = X/6 + 9
X = 72
- 54 - 7X = 36 - 2X
X = -18
4X + 4(X + 9) = -20
X = - 7
(9X + 15)/ - 6 = 14
X = -11
The sum of three consecutive numbers is 120. What is the smallest of these numbers?
3X + 3 = 120
X = 39
X/ - 11 + 1 = - 2
X = 33
-27 - 4X = - X + 30
X = - 19
6X + 6(- 3x - 9) = - 198
X = 12
(- 11X - 7)/ - 8 = 16
X = 11
The sum of three consecutive even numbers is 150. What are the three numbers?
3X + 6 = 150
48, 50, 52
