Question 901276: Please help me with this problem thank you!
S=a-rl/l-r find a
Answer by persian52(161) (Show Source): You can put this solution on YOUR website!
a−rl/−r=S
Since −r and −r are like terms, subtract r from −r to get −2r.
a−2r=S
Since −2r does not contain the variable to solve for, move it to the right-hand side of the equation by adding 2r to both sides.
a=2r+S
