7. Solve each of the following equations.

(a) \(\dfrac{w}{5} = 10\) [1]

(b) \(\dfrac{42}{x} = 7\) [1]

Mark scheme (a)

Scheme	Marks	Comments
(w =) 50	B1	Accept embedded answer. Mark final answer.

Mark scheme (b)

Scheme	Marks	Comments
(x =) 6	B1	Accept embedded answer. Mark final answer. (x =) 42/7 is B0.

Mark scheme (c)

Scheme	Marks	Comments
13y – 9y = 27 + 5	B1	To gain the first two B1 marks there must be an equation. Accept embedded answer. F.T. until 2^nd error.
4y = 32	B1
y = 8	B1	32/4 not accepted as final answer. If FT leads to a whole number answer, it must be shown as a whole number. Otherwise accept a fraction. Mark final answer.
