Question 463702: help?! please show all work so i know how to actually do these.
solve for the unknown and check the work.
1. 4√x=20
2. √y+√y+7=7
3. √x+11=√x+1
if its confusing.. in number 2 the √y+7 is a square root
and in number 3 the x+11 is one square root and x+1 is another one. just so you dont think that just the y is or just the x. (:
