Answer 1

Answer:

i. dont no dear ok thanks

Answer 2

Step-by-step explanation:

(i).

$7x + 5y - 2x + 9y$

solution:-

$7x - 2x + 9y+ 5y$

You get your answer:-

$5x + 14y$

(ii).

$8a²- 3a + 7a -8a²$

solution:-

$7a- 3a -8a² + 8a²$

you get your answer:-

$4a$

(iii).

$-3x² + 9xy - 10 + 4x²- xy + 8$

solution :-

$-3x² + 4x²+ 9xy - xy + 8- 10$

you get your answer:-

$x²+ 8xy + 2$

(iv).

$6ab +6bc-5ac + 10 - 7bc + 2ab - 2ac$

solution:-

$6ab + 2ab+6bc- 7bc-5ac -2ac + 10$

you get your answer:-

$4ab- bc-3ac + 10$

(v).

$12 + 7xy - 3y²+ 2y²- 10xy + 8$

solution:-

$7xy- 10xy - 3y²+ 2y² + 8 + 12$

youget your answer:-

$- 3xy - y² + 20$

Thank you bro
