Answer»

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
= 60 (10, 5, 12, 15)


(b) n
+ 12 = 20 (12, 8, 20, 0)


(c) p
− 5 = 5 (0, 10, 5 − 5)


(d) (7,
2, 10, 14)


(e) r
− 4 = 0 (4, − 4, 8, 0)


(f) x +
4 = 2 (− 2, 0, 2, 4)
