Step-by-step solution

2 steps
  1. Determine the domain of the variables.

    For the square roots to be defined, the expressions under them must be non-negative:

    4x−3≥0  ⟹  4x≥3  ⟹  x≥344x-3 \ge 0 \implies 4x \ge 3 \implies x \ge \frac{3}{4} 5x+1≥0  ⟹  5x≥−1  ⟹  x≥−155x+1 \ge 0 \implies 5x \ge -1 \implies x \ge -\frac{1}{5}

    Combining these conditions, we must have x≥34x \ge \frac{3}{4}. Since xx is specified as an integer, xx must be 1,2,3,…1, 2, 3, \dots.

  2. Isolate one of the radical terms.

    Move the second radical term to the right side of the equation
