Algebra 1 help needed.?

Question

a. Solve ry+s= tx-m for y. Explain each step in your solution.
b. Would there be any limitations for the value of each variable? If so explain the limitation.

Answer 1

ry +s = tx - m
You must leave y alone for indicate its value in terms of other variables.

First of all you move the s to the other side or the = as shown: ry =tx- m - s (you change the sign of s)

Then you move the r as follows: y=(tx-m-s)/r

And thats it

You have a restriction because the r has to be different than 0 to avoid a division by zero. So restriction is r different from zero.

Answer 2

ry + s = tx - m

ry = tx -m -s (subtract s from each side)

y = (tx -m -s ) / r (divide each side by r)

Answer is y = (tx -m -s ) / r where r is not equal to 0
