simplify (7mn-2m+n-5)-(mn+2m-2)

simplify

(7 mn - 2 m + n - 5) - (mn + 2 m - 2)

6 mn - 4 m + n - 3

Solution steps

(7 mn - 2 m + n - 5) - (mn + 2 m - 2)

Apply rule:

(a) = a

(7 mn - 2 m + n - 5) = 7 mn - 2 m + n - 5

= 7 mn - 2 m + n - 5 - (mn + 2 m - 2)

Apply the distributive law:

- (a + b) = - a - b

- (mn + 2 m - 2) = - mn - 2 m + 2

= 7 mn - 2 m + n - 5 - mn - 2 m + 2

Group like terms

= 7 mn - mn - 2 m - 2 m + n - 5 + 2

Add similar elements:

7 mn - mn = 6 mn

= 6 mn - 2 m - 2 m + n - 5 + 2

Add similar elements:

- 2 m - 2 m = - 4 m

= 6 mn - 4 m + n - 5 + 2

Add the numbers:

- 5 + 2 = - 3

= 6 mn - 4 m + n - 3
