Answer:

x = (274/25)

Explanation:

STEP 1:Isolate the square root on the left hand side

STEP 2:Eliminate the radical on the left hand side

STEP 3:Solve the linear equation

STEP 4:Check that the solution is correct

Original equation, root isolated, after tidy up 5√x+2 = 18 Plug in (274/25) for x 5√(274/25)+2 = 18 Simplify 5√12.96 = 18 Solution checks !! Solution is: x = (274/25)
