Solve

ã9x+67=x+5

1. Steve

Sure, we'll help. Where do you get stuck?

2. Lavern

i have no clue how to solve

3. Reiny

do you mean
√(9x+67) = x+5 or
√(9x) + 67 = x+5 ?

hint: square both sides of the equation.

4. Steve

If I asked you to solve

√x = 5

could you solve that?
Sure. You'd just say

x = 5^2 = 25

same thing here

√9x+67 = x+5
9x+67 = (x+5)^2

expand the right side, collect terms, and solve the quadratic.

If that mystifies you, you're in big trouble. See someone in person for help.
