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,

$\frac{1}{2}x=u+6$

Now,

From the given equation,

$\frac{1}{2}x=u+6$

Then,

$\begin{gathered} \frac{1}{2}x=u+6 \\ \frac{1}{2}x-u-6=0 \end{gathered}$

Then,

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

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,

$x=-q+26$
