Write the formula.
• Double a number n
then take away 6 to
give an answer a.
2n - 6 = a
Write the formula.
• Halve a number x
then add 4 to give
the number y.
x
+4= y

Write the formula.
• Multiply a number p
by 6 then subtract 4
to give the answer r.
6p -4 = r
Write the formula.
• Add 3 to a number
m then multiply this
all by 4 to give q.
4( m + 3) = q
Write the formula.
• First add 6 to a
number p then
divide by 3 to get
the final answer r.
p+6
r=

Write the formula.
• From 16 take away
2 times a number n
to give the answer c.
c =16 - 2n
Write the formula.
• From 21 take away
3 times a number z
to give the final
answer e.
e = 21- 3z
Write the formula.
• From 16 take away
a number n then
divide by 3 to get
the final answer p.
16 - n
p=

Write the formula.
• Multiply a number d
by a half then add 6
to give the number
e.

Write the formula.
• Subtract 6 from a
number n and then
divide by 2 to give
the number j.
