One-Step Equations
4 = -8 + x
x= 12
6x – 13 = 11
x= 4
4x + 3 = 7x-6
x = 3
x - 2 = 6
x = 8
What is the 4 Basic Operations?
Add, Subtract, Multiply and Divide
x + 12 = 0
x= -12
3x + 5 = 14
x= 3
2(5 + 5x) = 60
x = 5
-5p + 1 = 6
p = -1
What operation is the inverse of multiplication?
The inverse operations or opposite operations.
3 = -2 – x
x= -5
x/2 + 13 =-8
x= -42
3x - 45 = x + 7
x = -49
2n+10 = 4
n = -3
What operation is the inverse of division?
Multiplication
5x = -80
x= -16
x/2 + 5 =10
x= 10
14 = (3a + 6) + 2
a=2

2b
-16 = x+2
x= -18
x/3 - 6 = -3
x= 9
-21 = 7(5k - 8)
k = 1
3(𝑥 − 9) = −6(x+4)
x =1/3
When solving something like 3(x -2) = 4x
