Answer 2

Let's solve each equation step by step:

1. (875-75)*х = 800 First, simplify the left side of the equation: 800 = 800x

   Now, divide both sides by 800 to solve for x: x = 800/800 x = 1

2. (1025+75)*х = 1100 Simplify the left side of the equation: 1100 = 1100x

   Divide both sides by 1100 to find the value of x: x = 1100/1100 x = 1

3. (380+20)/х = 400 Combine the numbers on the left side of the equation: 400 = 400/х

   To isolate x, divide both sides by 400: 1/х = 1

   Now, take the reciprocal of both sides to solve for x: х = 1

4. (590-70)/х = 520 Combine the numbers on the left side of the equation: 520 = 520/х

   To isolate x, divide both sides by 520: 1/х = 1

   Again, take the reciprocal of both sides to solve for x: х = 1

Now, we have found that x = 1 in all four equations.
