1. One-Step Equations and Inequalities
Chapter
Six

2. Addition and Subtraction
15 + x = 31
x = 16
n + 9=27
-9 -9
n = 18
d – 11 = 47
+ 11 =+11
d =58
r – 8 = 13
r = 21

3. Alright, let’s try it!! x + 5 = 19 w – 14 = 89 b + 13 = 26 17 + y = 42
f + 15 = 45
m – 18 = 13

4. Multiplication and Division
a = 9
2x = 26
x = 13
n/9 = 4
(9) n/9 = 4(9)
n = 36
x/3 = 7
(3) x/3 = 7 (3)
x = 21

5. Alright, let’s try it!! 10y = 80 h/6 = 8 12a = 60 r/15 = -10 -3e = 36
w/4 = 19

6. Variables with a negative coefficient
-d = -27
(-1)(-d) = (-27)(-1)
d = 27
-276 = -c
(-1)(-276) = (-c)(-1)
276 = c

7. Let’s try it!!
-q = 7
-k = 13
-v = -9
-w = 17
-m = 875
-h = -379

8. Solving addition and subtraction inequalities
e < 92
x – 2 > 12
x > 14
34 + g > 89
g > 55
f – 12  25
f  37

9. Last one, let’s try it!! h + 12 < 87 i – 13 > 39 14 + j < 28
k – 939  27
m + 29 < 312
n – 825  56
