Question

a)4a+5a-9a+14a
b)15x-4x+(8x-5x)-10x
c)(17y+13y-6y)-(32y-23y)
d)-8a+6a-5a+(10a-3a+5a)-4a

Answer 1

a)4a+5a-9a+14a
=9a-9a+14a
=14a;

b)15x-4x+(8x-5x)-10x
=15x-4x+3x-10x
=11x+3x-10x
=4x;

c)(17y+13y-6y)-(32y-23y)
=24y-9y
=15y;

d)-8a+6a-5a+(10a-3a+5a)-4a
=2a-5a+12a-4a
=5a;

Answer 2

1) 5a+5a-9a+14a
(4+5-9+14)a=14a

2) 15x-4x+(8x-5x)-10x
15x-4x+(3x)-10x
15x-4x+3x-10x=4x

3)(17y+13y-6y)-(32y-23y)
(24y)-9y
24y-9y=15y

4)-8a+6a-5a+(10a-3a+5a)-4a
-8a+6a-5a+(12a)-4a
-8a+6a-5a+12a-4a
a
