Question

Rearrange the equation so u is the independent variable. -12u+13=8w-3

w= ___

Answer 1

w =
`(-12u+16)/(8)`

Explanation:

Reverse the equation placing w on the left side

8w - 3 = - 12u + 13 ( add 3 to both sides )

8w = - 12u + 16 ( divide both sides by 8 )

w =
`(-12u+16)/(8)`

Answer 2

`w = (4-3u)/(2)`

Explanation:

Given equation,

`-12u + 13 = 8w - 3`

For making u is as an independent variable we need to isolate w,

Add 3 on both sides,

`-12u + 13 + 3 = 8w`

`-12u + 16 = 8w`

Divide both sides by 8,

`(-12u+16)/(8)=w`

`(4(-3u+4))/(8)=w`

`(-3u+4)/(2)=w`

`\implies w = (4-3u)/(2)`

Which is the required equation.
