Question

2. (100 + x) = 400200+ (6 + 400) = 1 000700:y - 2 = 5(800 + x) - 300 = 600​

Answer 1

Ответ:

100+х=400:2

100х=200

х=2

700:у=5+2

у=100

800+х=600+300

800+х=900

х=900-800

х=100

Answer 2

Let's solve each equation step by step:

1. (100 + x) = 400 Subtract 100 from both sides: x = 400 - 100 x = 300

2. 200 + (6 + 400) = 1 000 Perform the addition inside the parentheses: 200 + (6 + 400) = 200 + 406 Add the numbers: 200 + 406 = 606

   The equation becomes: 606 = 1 000

   This equation is not true. It seems there might be an error or typo in the equation.

3. y - 2 = 5(800 + x) - 300 = 600 Distribute the 5 to the terms inside the parentheses: y - 2 = 5 * 800 + 5 * x - 300 Simplify the right side: y - 2 = 4,000 + 5x - 300 Combine like terms: y - 2 = 5x + 3,700

   Subtract 3,700 from both sides: y - 2 - 3,700 = 5x + 3,700 - 3,700 y - 3,702 = 5x

   Divide both sides by 5: (y - 3,702)/5 = 5x/5 y/5 - 3,702/5 = x

   Simplify the equation: y/5 - 740.4 = x

   Therefore, the equation is x = y/5 - 740.4.
