1.Leo is three times as old as his brother. His brother is x years old. Write down an expression for Leo's age.
(a)3x
(b)x − 3
(c)x/3
(d)x + 3
2.Explain why the equation 4x + 3 = 4x + 10 has no solution for x.
(a)Subtracting 4x gives 3 = 10, which is never true.
(b)x would have to be negative, but x must be positive.
(c)It's true for every x, so there are infinite solutions.
(d)x = 7, since 10 − 3 = 7.

(a)100/3
(b)25
(c)24
(d)50/3
