Question

(vi) p + (-9-r-s) - (p-9-)
(viii) 3x + (8x - 5x) - (7x - x)
(x) 6a² + (2a2 - a?) - (a2 - 62)
(xii) -m-n-(-m) - m
(xiv) 25y - (5x - 10y + 6x - 3y)
(xvi) a - (2a - 4a + 3a) Solve this!!​

Answer 1

Answer:

(xvi) a=0

=a-(5a-4a)

=a-a

=0

question vi is incomplete

(vii)x=0

I.e.=3x+3x-6x

= 6x -6x

=0

(xii) m=- n

=-m-n+m-m

=-m-n

m=-n

(xiv)x=

=25y-(11x-13y)

= 25y- 11x +13y

11x=38y

x=38y/11
