Question

(7200-a*200)+200=3400 ??? ??? ??? ??? ???

Answer 1

7200-a*200=3400-200
7200-a*200=3200
-200а=3200-7200
-200а=-4000
А=-4000:(-200)
А=20

Answer 2

Let's solve the equation step by step:

(7200 - a * 200) + 200 = 3400

First, we can simplify the expression inside the parentheses:

7200 - a * 200 + 200 = 3400

Next, we combine like terms:

7200 - a * 200 + 200 = 3400

Now, we can subtract 7200 from both sides to isolate the term with "a":

-a * 200 + 200 = 3400 - 7200

Simplifying further:

-a * 200 + 200 = -3800

Next, we can move the 200 to the other side of the equation by subtracting it:

-a * 200 = -3800 - 200

Simplifying further:

-a * 200 = -4000

To solve for "a," we divide both sides of the equation by -200:

-a * 200 / -200 = -4000 / -200

Simplifying:

a = 20

Therefore, the value of "a" that satisfies the equation (7200 - a * 200) + 200 = 3400 is a = 20.
