(a)[2]
Solve the equation $4(p-3) = 2p + 7$.
(b)[3]
Solve the following simultaneous equations. $2x - y = 5$ $7x + 2y = 1$ Show your working.
(c)[3]
Simplify $\dfrac{m^2 + 3m}{2m^2 + 5m - 3}$ by factorising.
(d)[3]
Because $b$ is directly proportional to the cube of $a$. Given that $b=4$ when $a=2$, find the value of $b$ when $a=5$.
