A letter represents a variable - (an unknown value)
When students solve equations they need to follow the rule: BEDMAS
Brackets
Exponents
Divide
Multiply
Addition
Subtraction
Find the value of the variable:
4r = 16
10p = 30
x ÷ 2 = 12
n ÷ 12 = 10
x + 6 = 12
y - 3 = 8
n + 32 = 40
13 + t = 21
17q = 34
t ÷ 150 = 2
Find the value of the variable:
3x + 3 = 12
10p - 4 = 16
11y + 5 = 27
4n - 3 = 9
17x - 2 = 32
12p - 27 = 9
(q ÷ 3) + 4 = 16
(n ÷ 2) - 3 = 4
8 ÷ y = 4
4x ÷ 2 = 3

Find the value of the variable making sure you work out what is inside the brackets first.
P = 5 + (3 - 2)
Q = (5 + 3) - 2 =
S = 3 x (6 + 9)
T = (3 x 6) + 9
U = (5 + 2) x (4 - 1)
V = 5 + (2 x 4) - 1
W = (9 + 3) x 5
X = 9 + (3 x 5)
G = (4 - 9) x 3
H = 4 - (9 x 3)
