Pick out the solution from the values given in the bracket next to each equation. Show that the other values do not satisfy the equation.
(a)5m=605m=60(10, 5, 12, 15)
(b)n+12=20n+12=20(12, 8, 20, 0)
(c)p–5=5p–5=5(0, 10, 5, –5)
(d)q2=7q2=7(7, 2, 10, 14)
(e)r–4=0r–4=0(4, –4, 8, 0)
(f)x+4=2x+4=2(–2, 0, 2, 4)
