Answer 1

Ответ:

Пошаговое объяснение:

а)6m+5n-4n-4m+3n+m=3m+4n

б)7m+6n-5n-8m+3n+m=4n

в)7х-8у+9у-5х+6=2х+у+6

г)3х-5у+7у-2х+4=х+2у+4

д)3(2х-3у)+9(у-4х)=6х-9у+9у-36х=-30х

е)7(2х-3у)-3(4х+2у)=14х-21у-12х-6у=2х-27у

Answer 2

Ответ:

Пошаговое объяснение:

a)6m+5n-4n-4m+3n+m = 3m+4n

б)7m+6n-5n-8m+3n+m = 4n

в)7х-8у+9у-5х+6 = 2x+y+6

г)3х-5у+7у-2х+4 = x+2y+4

д)3(2х-3у)+9(у-4х) = -30x

е)7(2х-3у)-3(4х+2у) = 2x-27y

Answer 3

Let's simplify each expression step by step:

a) 6m + 5n - 4n - 4m + 3n + m = (6m - 4m + m) + (5n - 4n + 3n) = 3m + 4n

b) 7m + 6n - 5n - 8m + 3n + m = (7m - 8m + m) + (6n - 5n + 3n) = 0m + 4n = 4n

в) 7x - 8y + 9y - 5x + 6 = (7x - 5x) + (-8y + 9y) + 6 = 2x + y + 6

г) 3x - 5y + 7y - 2x + 4 = (3x - 2x) + (-5y + 7y) + 4 = x + 2y + 4

д) 3(2x - 3y) + 9(y - 4x) = 6x - 9y + 9y - 36x = -30x - 9y

е) 7(2x - 3y) - 3(4x + 2y) = 14x - 21y - 12x - 6y = 2x - 27y

So, the simplified forms of the given expressions are:

a) 3m + 4n b) 4n в) 2x + y + 6 г) x + 2y + 4 д) -30x - 9y е) 2x - 27y
