Question

Changing the subject of a formula making x the subject of each formula

Answer 1

As per given by the question,

there are given that the equation,

`(1)/(2)x=u+6`

Now,

From the given equation,

`(1)/(2)x=u+6`

Then,

`\begin{gathered} (1)/(2)x=u+6 \\ (1)/(2)x-u-6=0 \end{gathered}`

Then,

`\begin{gathered} (1)/(2)x-u-6=0 \\ (1)/(2)x=u+6 \\ x=(u+6)/((1)/(2)) \\ x=2(u+6) \end{gathered}`

Hence, the value of the x is,

`\begin{gathered} x=2(u+6) \\ x=2u+12 \end{gathered}`

For Part 7:

The given equation is,

`1-13w=2h+x`

Then,

`\begin{gathered} 1-13w=2h+x \\ 1-13w-2h-x=0 \\ 1-13w-2h=x \end{gathered}`

Hence, the value of x is,

`x=1-13w-2h`

Now,

For part 10:

The given equation is,

`5=x-21+q`

Then,

`\begin{gathered} 5=x-21+q \\ 5-x+21-q=0 \\ 26-x-q=0 \\ x=-q+26 \end{gathered}`

Hence, the value of x is,

`x=-q+26`
