Question

(7200-a×200)+2000=3400

Answer 1

Если надо была найти а, то а=-29

Answer 2

(7200-200а)+2000=3400
9200-200а=3400
-200а=-5800
а=29

Answer 3

Let's solve the equation step-by-step:

Given equation: (7200 - a × 200) + 2000 = 3400

Step 1: Simplify the expression inside the parentheses. 7200 - a × 200 = 7200 - 200a

Step 2: Combine like terms on the left side of the equation. (7200 - 200a) + 2000 = 7200 + 2000 - 200a = 9200 - 200a

Step 3: Now, we have the equation: 9200 - 200a = 3400

Step 4: Isolate the term with 'a' on one side by moving the constant term to the other side. 9200 - 3400 = 200a 5800 = 200a

Step 5: Divide both sides by 200 to solve for 'a'. a = 5800 / 200 a = 29

So the value of 'a' that satisfies the equation is 29. Let's verify by substituting 'a' back into the original equation:

(7200 - 29 × 200) + 2000 = 3400 (7200 - 5800) + 2000 = 3400 1400 + 2000 = 3400 3400 = 3400

The equation is balanced, and 'a = 29' is indeed the correct solution.
