Question

Solve the equation sx+tx=r for x.

Answer 1

Step-by-step explanation:

Consider the following algebraic equation:

`sx\text{ + tx = r}`

Applying a common factor on the left side of the equation, we get:

`x(s+t)=r`

finally, solving for x, we obtain:

`x\text{ =}(r)/(s+t)`

we can conclude that the correct answer is:

Answer:
`x\text{ =}(r)/(s+t)`
