Question

(i) 3a²b, -4a4b, 9a-b
Subtract:
(i) -5ab from 12ab
iii) 2x – y from 3x - 5y
Subtract 3x - 4y-7z fror​

Answer 1

Answer:

(1) 12ab-5ab= 7ab

(2) 3x-5y-2x+y= x-4y

Answer 2

Answer:

Step-by-step:

There is not anything given so I will subtract .

(i) 3a²b, -4a4b, 9a-b

3a²b - (-4a4b) - (9a-b)

9a + b + 4a - 4b - 9a + b

(9a+4a-9a) + (b-4b+b)

4a+(-2b)

4a-2b

(ii) -5ab from 12ab

12ab - (-5ab)

12ab + 5ab

17ab

(iii) 2x – y from 3x - 5y

(3x - 5y) - (2x – y)

3x - 5y - 2x + y

(3x - 2x) + (-5y + y)

x + -4y

Subtract 3x - 4y-7z

This can be solved when their value is given or when there are more terms.
