10m+7n-14

Step-by-step explanation: The answer is 10m + 7n - 14

Step-by-step explanation:

Q = 7m + 3n

R = 11 - 2m

S = n + 5

T = -m - 3n + 8

[Q - R] + [S - T] is

[ 7m + 3n - (11 - 2m) ] + [ n + 5 - ( - m - 3n+8)]

Solve the terms in the bracket first

That's

( 7m + 3n - 11 + 2m ) + ( n + 5 + m + 3n - 8)

( 9m + 3n - 11 ) + ( m + 4n - 3)

Remove the brackets

That's

9m + 3n - 11 + m + 4n - 3

Group like terms

9m + m + 3n + 4n - 11 - 3

10m + 7n - 14

Hope this helps you haru8355 Step-by-step explanation:

Given : , , , and Now  ,  [ ∵ (-)(+)=(-) and (-)(-)=(+)]

[Note : when -1 is outside the parenthesis it indicates that -1 should be multiplied with each of the terms present inside the parenthesis .] [Combine like terms.]  [ ∵ (-)(+)=(-) and (-)(-)=(+)] [Combine like terms.]

Now,   [combine like terms]

10m - 7n - 14

Step-by-step explanation:

Given Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8

[Q - R] + [S - T].

= (7m + 3n - 11 + 2m) + (n + 5 + m + 3n - 8)

collect all the like terms

= 7m +2m +m +3n + n + 3n - 11 - 8 + 5

= 10m + 7n - 14

The third option  10m - 7n - 14 is right CrsvrBryan7852
10m + 7n - 14

Steps:
[7m + 3n -(11 - 2m)] + [n + 5 -(-m -3n + 8)]
7m + 3n -11 + 2m + n + 5 + m + 3n - 8
