Question

subtract
4mn-7m+4n from 5n+8mn+4m

Answer 1

Answer:

4mn + 11m - 1n

Step-by-step explanation:

5n + 8mn + 4m - (4mn -7m + 4n)

We can rearrange the terms as,

8mn + 4m + 5n - (4mn -7m +4n)

  8mn + 4m + 5n

- 4mn + 7m - 4n     (removing the brackets)

= 4mn + 11m - 1n

Therefore the answer is 4mn + 11m - 1n.

Answer 2

Given,

• 4mn-7m+4n
• 5n+8mn+4m

To find,

• We have to subtract 4mn-7m+4n from 5n+8mn+4m.

Solution,

The subtraction of 4mn-7m+4n from 5n+8mn+4m gives n +4mn +11 m.

We have to subtract 4mn-7m+4n from 5n+8mn+4m, then

         = 5n + 8mn + 4m -(4mn - 7m +4n)

           Removing the brackets, we get

         = 5n + 8mn +4m -4mn +7m -4n

   Now, simplifying by performing mathematical operations on like terms,

         = 5n -4n + 8mn-4mn +4m +7m

         = n +4mn +11 m

∴ The subtraction of 4mn-7m+4n from 5n+8mn+4m gives n+4mn +11m.

Hence, the subtraction of 4mn-7m+4n from 5n+8mn+4m gives n +4mn +11 m.
