Question

2350:x-17=33 Y:12+15=21 2320-x:4=1990 1960-200:x=1910

Answer 1

2350:х-17=33. 2350:х=33+17. 2350:x=50 x=2350:50 x=47

Answer 2

Let's solve each of these equations one by one:

1. 2350 - x - 17 = 33 Simplifying the left side by combining like terms, we get: 2333 - x = 33 Subtracting 2333 from both sides, we get: -x = -2300 Dividing both sides by -1, we get: x = 2300

   Therefore, the solution to this equation is x = 2300.

2. y:12 + 15 = 21 Subtracting 15 from both sides, we get: y:12 = 6 Multiplying both sides by 12, we get: y = 72

   Therefore, the solution to this equation is y = 72.

3. 2320 - x:4 = 1990 Multiplying both sides by 4, we get: 9280 - x = 7960 Subtracting 9280 from both sides, we get: -x = -1320 Dividing both sides by -1, we get: x = 1320

   Therefore, the solution to this equation is x = 1320.

4. 1960 - 200:x = 1910 Adding 200/x to both sides, we get: 1960 = 1910 + 200/x Subtracting 1910 from both sides, we get: 50 = 200/x Multiplying both sides by x, we get: 50x = 200 Dividing both sides by 50, we get: x = 4

   Therefore, the solution to this equation is x = 4.
