Answer 1

#2 ok
#3 10-6 = 4
#4 divide first by -2:
-2(m-30)=-6m
m-30 = 3m
#5 Collect everything on the left:
3.75x+3.7=1.7+1.75x
2x+2 = 0

Answer 2

2. correct
3.incorrect, C.20

5.incorrect, B.-1
Hoped I helped!

Answer 3

#2 - ok

#3
x/5+6=10
x/5=4
x = 20

#4
-2(m-30) = -6m
-2m + 60 = -6m
4m = -60
m = -15

#5
3.75x+3.7=1.7+1.75x
2x = -2
x = -1
