One Step Equations
The inverse of addition is -
subtraction
Solve: 3x = 36
x = 12
p = 9
Less than symbol
<
c > 20
The inverse of multiplication is -
division
Solve: v / - 2 = 12
v = -32
Solve: 6-6x = 108
x = -17
Greater than symbol
>
horizontal number line on a coordinate plane
x-axis
Solve: x + 14 = 30
X = 16
Solve: -16 = -p
p = 16
Solve: 3-p = -12
p = 15
Open circle
means not equal to that value
vertical number line on a coordinate plane
Solve: m - 8 = -10
m = -2
x = -5
