Question

Solve sx+tx=r for x.
(Explain how to do it please. :). Because I have no idea how to do this.)

Answer 1

Step-by-step explanation:

solve for x.

sx+tx=r

Factor out variable x.

x(s+t)=r

Divide both sides by s+t.

so you get

x(s+t)/(s+t)=r/(s+t)

x=r/s+t

Answer 2

Given: Given expression is sx+tx=r.

To find: We have to find out the value of x.

Solution:

The expression is sx+tx=r.

To determine the value of x we have to take x as a common term in the above expression.

Then we will get a term which is multiple of x.

Now the division result of r to the term give the value of x.

$sx + tx = r \\ x(s + t) = r \\ x = \frac{r}{s + t}$

So, the value of x is $\frac{r}{s + t}$.
