Final answer:
To find the value of x, substitute the given values into the equations and solve for x.
Step-by-step explanation:
To find the value of x, we need to use the information given. We are given that em = 3x - 1, ml = x2, and el = 9. Substitute the given values into the equations and solve for x.
Substituting the values, we have 3x - 1 = 9, which gives us 3x = 10. Divide both sides by 3 to find that x = 10/3. Therefore, the value of x is approximately 3.333.
