Question

(i) − ( + )_________________________________

(ii) − − ___________________________________
(iii) − − ____________________________________
(iv) − ________________________________
(v) −5y

Answer 1

-5y

Explanation:

We are to simplify the expression

5x - 5(y+x)

Open the bracket by applying the distributive law;

5x-(5(y)+5(x))

5x - (5y+5x)

5x - 5y - 5x

Collect like terms to have:

5x - 5x - 5y

0-5y

= -5y

Hence the simplified form is -5y
