Question

`12-7√(x-5) =4` How would I solve this?

Answer 1

Lets Solve!

1. Move 12 to the right side.

• 
  `-7√(x-5)=-8`

2. Divide both sides by -7.

• 
  `(-7√(x-5) )/(-7) =(-8)/(-7)`

3. Simplify.

• 
  `√(x-5)=(8)/(7)`

4. Square both sides.

• 
  `x-5=(64)/(49)`

5. Solve
`x-5=(64)/(49)`

• 
  `x=(309)/(49)`

Hence, our solution.
