The value of x is 4

Step-by-step explanation:

The formula for simple interest is:

[tex]Simple\ interest = P *r * t[/tex]

Here

P is principal amount

r is interest rate

and t is the time in years

We know

Interest = $840

Rate = r = 5%

P = $4200

Putting the values in the formula

[tex]840 = 4200 * 0.05 * t\\840 = 210 * t\\t = \frac{840}{210}\\t = 4[/tex]

Hence,

The value of x is 4
