[SIZE=3]& # 8 7 3 0 ;

x-2(√(x-3) = 3

so I substract the x from both sides but then what? do I square both sides or do I divide by 2 and make the other side a fraction?

√(5x+1) = x+1

I can get it down to x(x-3) but then I am stuck. So yeah ok 3 works, but how was I supposed to know 0 works to?

also why does √x-3 not equal x+9 ? isn't -3*-3 = +9?

dang is there a way to make the square root symbol extend across the numbers?
