Question

(31*550-x) *120=10200 17050-x=10200:120 17050-85 x=16965 (31*550-16965)*120=10200

Answer 1

Відповідь:(31*550-x)*120=10200

31*550 -х = 10200 : 120

17050 -х = 85

17050 -85 = х  

х = 16965

Answer 2

It looks like you're working with some mathematical equations. Let's break down your calculations step by step to ensure accuracy:

1. Equation 1: $(31 \times 550 - x) \times 120 = 10200$
2. Equation 2: $17050 - x = \frac{10200}{120}$
3. Solving Equation 2: $17050 - x = 85$ (since $10200 / 120 = 85$)
4. Solving for $x$ in Equation 2: $x = 17050 - 85 = 16965$
5. Substituting $x$ into Equation 1: $(31 \times 550 - 16965) \times 120 = 10200$

It seems like you've made an error in your calculations when solving Equation 2. The correct value of $x$ should be 16965, not 85. Let's reevaluate your calculations based on this:

1. Equation 1: $(31 \times 550 - x) \times 120 = 10200$
2. Equation 2 (corrected): $17050 - x = \frac{10200}{120}$
3. Solving Equation 2 (corrected): $17050 - x = 85$
4. Solving for $x$ in Equation 2 (corrected): $x = 17050 - 85 = 16965$
5. Substituting $x$ into Equation 1: $(31 \times 550 - 16965) \times 120 = 10200$, which is not true.

It seems there might be a mistake in your initial equation or calculations, as the final equation doesn't seem to be consistent. Please double-check your original equations and calculations to make sure they are accurate. If you provide more context or information, I'd be happy to help you further.
