2. K -11 +11 = -21 -11 K = -21-11 K = -21 + -11 K = -32 -12+w = -36
A# 2-1 NAME_______________________________________________________________DATE___________________PER._____ SOLVING ONE-STEP EQUATIONS Solve each equation, checking your solution on your calculator.
Ask yourself, “Self, what is the inverse operation of _____________________.”
K =
K =
K =
K = -32
-12+w = -36
w=+12-36
W= -23

3. Ask yourself, “Self, what is the inverse operation of _____________________.”
= m
-1.3 = m
0 = x + (-1.4)
= x
1.4 = x

4. Ask yourself, “Self, what is the inverse operation of _____________________.”

5. H- 26 = -29
H =
H = -3
X – (- 16) = 9
X – = 9
X = 9
X + 16 – 16 =
X = -5

6. 5x = -45
5x = -45 5
X = -9
-434 = -31y
-434 = -31 y
31 = 31 y
14 = y

7. -1 y = = -2 m
y = -8 * *6 = 3 * -2 m
Y = = m 2
-9 = m
1.7b = * 2 x = * 5
1.7 = =
b = X = -10 * =
2 2
X = 25

8. 14 = - 7 a 3
3 * 14 = * a =
42 = a 7
= a
- |x| + a-b
- |-3| + 3-4
= -4
3 (3 - (2 * -1) ) – (2*3) + (3* -1)
3 (3 - (-1) ) – (6) + (-1)
3 (4) – (6) + (-1)
= 7
