Me ajudem, por favor!​

Answer 1

a) 2c-4-c = 2c-c-4 = c-4

b) 3×+3y-2×+2y = 3x-2x+3y+2y = x+5y

c) 15ab -9ba = 6ab

d) 2.3×-4+6 = 6x+2

e) 2a - 3.(12-3a)+5-a = 2a-9a-a-36+5 = -8a-29

f) 4y-5y+3×+7× = -y+10x

g) 2n-n+m+3n = 2n-n+3n+m = 4n+m

h) 8h+11k-8h+3k = 8h-8h+11k+3k = 14k

i) b+3c-b+4 = b-b+3c+4 = 3c+4

j) 35-4.(3+55)-1 = 35-12-220-1 = 35-233 = 198

k) v+v+v+v = 4v

l) 5c-7+12c-4 = 5c+12c-7-4 = 17c-11

m) 4.(5-3d)+2.(10-2d) = 20-12d+20-4d = -12d-4d = -16d
