# 1

We need to get x all by itself (ideally on the left side since that's common convention). So do that first. Then rearrange terms and divide both sides by rt to fully isolate x

s=rxt+

rxt+=+s

x%2A%28rt%29+=+s

x+=+s%2F%28rt%29

that finishes up problem #1

--------------------------------------------------------------

# 2

x is already on the left side, and there's only one copy of it, so we just divide both sides by "c-d" to undo the multiplication.

x%2A%28c-d%29+=+7-t

x+=+%287-t%29%2F%28c-d%29

and we're done
