One Step Equations
x + 7 = 18
x = 11
m + m + m =
3m
6c - 5 = 25
c = 5
a x b x c =
abc
What is a coefficient?
A coefficient is a number multiplied by a pronumeral (the number in front of a letter)
12 + m = 15
m = 3
7q - 4q =
3q
4y + 12 = 20
y = 2
6 x y x 8 x a =
48ay
What is a pronumeral?
A pronumeral is a symbol that represents an unknown quantity
H = 10
5m + 4y + 5m - 2y =
10m + 2y
6x + 2 = 14
x = 2
5 x b x 2 x b =
10b2
A constant is a number by itself
3p = 21
P = 7
6b - b =
5b
2x/4 = 5
x = 10
y x y x y x y
y3
What are terms?
Terms are numbers and pronumerals separated by the operation sign
t/4 = 4
t = 16
5 x b x 4 =
20b
4n/4 = 4
n= 4
7 x m x 7 x n =
49mn
What are like terms?
Like terms have exactly the same variable and exactly the same power, however can have different coefficients
