One-Step Equations
4 = -8 + x
x= 12
6x – 13 = 11
x= 4
-72 = x - 34
x = -38
x - 2 = 6
x = 8
This is how many operations are in a one step equation.

These are the 4 Basic Operations?
Add, Subtract, Multiply and Divide
x + 12 = 0
x= -12
3x + 5 = 14
x= 3
4x + 3 = 7
x = 1
-5p + 1 = 6
p = -1
These two terms are able to be added together.

The opposite of addition.
Subtraction
3 = -2 + x
x= 5
x/2 + 13 =-8
x= -42
4x + 5x - 2 = 34
x = 4
2n+10 = 4
n = 2
Which of these is an equation that has to be simplified before being solved
4x+3=11
-4x+2-7
5(y+2/5)=-13
4m+7m=12
5(y+2/5)=-13
What you must do to the operations in order to solve an equation.
The inverse or opposite of the operation.
5x = -80
x= -16
x/2 + 5 =10
x= 10
14 = (3a + 6) + 2
a=2
5(m-3) = 4
m = 19/5
This tells us the order in which to solve equations
Simplify the expression: 2(7x + 11)
14x + 22
-16 = x+2
x= -18
4/5x - 6 = -38
x= -40
-8 = 7(5k - 8) + 13
k = 1
3(𝑥 − 9) = −3
x = 8
This rule is ALWAYS applied when solving equations.
Golden Rule of Algebra or what you do to one side, you do to the other side.
When solving something like 8=4(x-7), what do you do first?
