denominator
Name at least three
careers where you would
need to use equations
(excluding teaching!)
Solve equations by using
inverse operations to
transform both sides of
the equation
in the same way.
x and ÷
+ and -
1) Solve these equations
a) 3b = 12
2
b) 2 + y = 3
9
c)
d) 3x + 9 = 5
2
e) 2p – 4 = 3p
2
f) 22 – 3a = 4a - 6
32 = 10
d-2
Find the value of x, and
hence the area and
perimeter of the square
2x + 1
2) Solve equations involving brackets
a) 3(m + 2) = 3
5
The sides of a square are 2x
+1 cm and 21 – 3x in length.
b) 8(n – 1) = 3n – 4

3)The answer to the equation x3 – 2x = 88 lies
between 4 and 5 Solve by trial and error to 1 d.p.
