Question

(2200+9(400-20х)×5)÷50+6×12=125

Answer 1

476-18x=125 |*(-1)
18x-476=-125
18X=601
X= 33.3(8)

Answer 2

Let's break down the given expression step by step:

First, let's simplify the expression within the parentheses:

400 - 20x = 400 - 20x

Next, we multiply the result by 9:

9(400 - 20x) = 3600 - 180x

Now, let's multiply the previous result by 5:

9(400 - 20x) × 5 = 5(3600 - 180x) = 18000 - 900x

Moving on, we add 2200 to the previous result:

2200 + 9(400 - 20x) × 5 = 2200 + (18000 - 900x) = 20200 - 900x

Now, let's divide the previous result by 50:

(2200 + 9(400 - 20x) × 5) ÷ 50 = (20200 - 900x) ÷ 50 = 404 - 18x

Next, let's calculate 6 multiplied by 12:

6 × 12 = 72

Finally, we add the previous result to 72:

(2200 + 9(400 - 20x) × 5) ÷ 50 + 6 × 12 = (404 - 18x) + 72 = 476 - 18x

So, the simplified expression is 476 - 18x.

However, it seems that the given expression in the question does not equal 125. Double-check the calculations or provide additional information if needed.
