I was hoping that some one could review my answers and tell me if im correct or not ^^
1. -2 (m-30)=-6m
a)-15
b)-13*****
c)-8
d)8
2. 3.75x + 3.7=1.7 + 1.75x
a)10*****
b)-1
c)1
d).1
3.-9 - 6(w+5)
a)-15w + 5*****
b)-15w + 30
c)-6w + 39
d)-6w + 21
1.
- 2 ( m - 30 ) = - 6 m
- 2 m - 2 ∙ ( - 30 ) = - 6 m
- 2 m + 60 = - 6 m
Add 2 m to both sides
60 = - 4 m
Divide both sides by - 4
- 15 = m
m = - 15
2.
3.75 x + 3.7 = 1.7 + 1.75 x
Subtract 1.75 x to both sides
2 x + 3.7 = 1.7
Subtract 3.7 to both sides
2 x = - 2
Divide both sides by 2
x = - 1
3.
- 9 - 6 ( w + 5 ) = - 9 - 6 ∙ w - 6 ∙ 5 = - 9 - 6 w - 30 = - 6 w - 39
