Answer 1

1.
`(1)/(6)x=4` Multiply 6 on both sides

`(6)(1)/(6)x = 4(6)`

x = 24 [to check it, you can plug 24 in for x in the equation, and do the same for 1-9]

2.
`(5)/(6)n = 15` Multiply 6/5 on both sides

`((6)/(5) )(5)/(6)x=15((6)/(5))`

`x = (90)/(5)`

x = 18

3.
`(2)/(3)d=(14)/(15)` Multiply 3/2 on both sides

`((3)/(2) )(2)/(3)d=(14)/(15)((3)/(2))`

`d=(42)/(30)`

`d=(7)/(5)`

4.
`(3)/(4)w=(21)/(30)` Multiply 4/3 on both sides

`((4)/(3))(3)/(4)w=(21)/(30)((4)/(3))`

`w = (84)/(90)`

`w=(14)/(15)`

5.
`(3)/(5)t=12` Multiply 5/3 on both sides

`((5)/(3))(3)/(5)t = 12((5)/(3))`

`t=(60)/(3)`

t = 20

6.
`(1)/(8)a=(1)/(3)` Multiply 8/1 or 8 on both sides

`(8)(1)/(8)a=(1)/(3)(8)`

`a=(8)/(3)`

7.
`-(1)/(6)x = -5` Multiply -6/1 or -6 on both sides

`(-6)-(1)/(6) x = -5(-6)`

x = 30

8.
`(9)/(4) r=-(27)/(32)` Multiply 4/9 on both sides

`((4)/(9))(9)/(4) r=-(27)/(32) ((4)/(9))`

`r=-(108)/(288)`

`r=-(3)/(8)`

9.
`-(2)/(5) m=4` Multiply -5/2 on both sides

`(-(5)/(2))-(2)/(5)m=4(-(5)/(2) )`

m = -10
