Question

Solve each equation for the specified variable

2) 9wr=81, solve for w
3) 2d-3f=9, solve for f
4) P=(g-9)180, solve for g
5)4x+y-5h=10y+u, solve for x

Answer 1

2) 9wr=81, solve for w
wr = 9
w = 9/r

3) 2d-3f=9, solve for f
-3f = 9 - 2d
f = (9 - 2d)/ -3
f = -3 + 2/3(d)

4) P=(g-9)180, solve for g
g - 9= P/180
g = P/180 + 9

5)4x+y-5h=10y+u, solve for x
4x = 10y + u - y + 5h
4x = 9y + u + h
x = (9y + u + h) / 4

Answer 2

Answer and Explanation:

Solve each equation for the specified variable :

1)
`9wr=81`

Solve for w,

Divide both side by 9r,

`w=(81)/(9r)`

`w=(9)/(r)`

2)
`2d-3f=9`

Solve for f,

`3f=2d-9`

`f=(2d-9)/(3)`

3)
`P=(g-9)180`

Solve for g,

`g-9=(P)/(180)`

`g=(P)/(180)+9`

4)
`4x+y-5h=10y+u`

Solve for x,

`4x=10y+u+5h-y`

`4x=9y+u+5h`

`x=(9y+u+5h)/(4)`
