• razy ;)

Answer 1

A) - ½(5b - 1) =-2½+½½
b) (8c+2) :2=4c+1
c)(-d+3)•(-1)=d-3
d) ½x-5•2=½x-10
e)-3+12:3=-3+4=1
f) 6b-6a+2b=8b-6a

Answer 2

A) =½-⁵/₂b
b) =4c+1
c) =d-3
d) =½x-10
e) =1
f) = 8b-6a

Answer 3

A) - ½(5b - 1) = - 5/2 b + 1/2
b) (8c+2) :2= 4 c +1
c) )(-d+3)•(-1)= d - 3
d)½x-5•2=1/2x - 10
e)-3+12:3= -3 + 4 = 1
f) 6b-6a+2b= 8b - 6a
