Josue knows that his aunt earns more money. than his uncle. He asked how much his aunt earns each month and was told, "$600 less

Firdavs [7]

Answer:

Uncle's earnings is $2400

Step-by-step explanation:

Represent his uncle's earnings with x

$600 less than twice what your uncle earns is represented as:

$2x - 600$

Since, his aunt's earnings is $4200.

We have:

$2x - 600 = 4200$

Add 600 to both sides

$2x - 600 + 600= 4200 + 600$

$2x = 4800$

Solve for x

$x = 4800/2$

$x = 2400$

<em>Hence, His uncle's earnings is $2400</em>
