Question

4000 + 5a = 3 000 + 3 000​

Answer 1

Ответ:

$a=400.$

Пошаговое объяснение:

$4000+5a=3000+3000\\4000+5a=6000\\5a=6000-4000\\5a=2000\\a=\frac{2000}{5}=400$

Answer 2

5а=6000-4000

5а=2000

а=2000:5

а=400

4000+5•400=3000+3000

Answer 3

To solve the equation, you want to isolate the variable "a" on one side of the equation. Here's the step-by-step process:

1. First, combine like terms on both sides of the equation:

4000 + 5a = 3000 + 3000

2. Simplify the equation:

4000 + 5a = 6000

3. Now, we want to isolate the variable "a" on one side, so let's get rid of the constant term "4000" on the left side. To do that, subtract 4000 from both sides of the equation:

4000 - 4000 + 5a = 6000 - 4000

5a = 2000

4. Finally, to solve for "a," divide both sides by 5:

a = 2000 / 5

a = 400

So, the value of "a" that satisfies the equation is 400.
