Tolonngg y jgn lup pke carany

a. 4x-3y +(2x+5y) = 6x + 2y
b.2m-10 +(21-3n)= 2m+ 21-10 -3n = 2m-3n+11
c.5x-10y+5+(-4y+12)= 5x-14y +17
d.2p-3q-1+(-p+q+3)= p-2q+2

operasikan yang variabel sama.
semoga membantu :)

Saya coba bantu jawab yah !

Penyelesaian :
---------------------

a. (4x - 3y) + (2x + 5y)
= 4x - 3y + 2x + 5y
= 4x + 2x - 3y + 5y
= 6x + 2y

b. {2 (m - 5)} + {3 (7 - n)}
= (2m - 10) + (21 - 3n)
= 2m - 10 + 21 - 3n
= 2m - 3n - 10 + 21
= 2m - 3n + 11

c. {5 (x - 2y + 1)} + {-4 (y - 3)}
= (5x - 10y + 5) + (-4y + 12)
= 5x - 10y + 5 - 4y + 12
= 5x - 10y - 4y + 5 + 12
= 5x - 14y + 17

d. (2p - 3q - 1) + (-p + q + 3)
= 2p - 3q - 1 - p + q + 3
= 2p - p - 3q + q - 1 + 3
= p - 2q + 2

Semoga bisa membantu
