Answer:    = 7 (square both sides)  11x + 5 = 7² = 49 (subtract 5 from both sides)  11x = 44 (divide both sides by 11)  x = 4  substitute x = 4 into the left side of the equation and if equal to the right side, then it is the solution.   = = = 7 ← equals right side  then x = 4 is the solution    I hope this helps!!  ~Karly
