2. ALGEBRA REVIEW 4) Formulae Substitution The formula t = v – u a
is used to calculate time (t).
If v = 21, u = 6 and a = 3, calculate what t will be?
If v = 14, u = 2 and t = 3, calculate what a is?
Substitution
a = 3, b = 5, c = -2, d = 10
(a) 3b – d (b) ac + b
(c) b(4a – 3) (d) a(2b + c) 4
Expand brackets
