Explanation of Solution

Given: Inequality: 1+5x>53x

Formula Used:

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value.

Real number line is the line whose points are the real numbers. 

Calculation:

Given: Inequality equation is 1+5x>53x

Solving the above equation, we have:

Subtract (1) from both the sides -

  1+5x1>53x1

Solving further:

  5x>43x

Add (3x) to both the sides -

  5x+3x>43x+3x

Solving further:

  8x>4

Divide both the sides by (8) and reversing the inequality, we have:

  8x8>48

  x>12

Drawing the above inequality on a real number line, we have:
