Answer 2

Solving the Equations

To solve the given set of equations, let's start by solving each equation step by step.

1. Solving the Equation c×210-900=12750: - First, add 900 to both sides of the equation to isolate the term with c: c×210 = 12750 + 900. - Then, divide both sides by 210 to solve for c: c = (12750 + 900) / 210.

2. Solving the Equation 4860-к×62=2442: - Begin by adding 62k to both sides of the equation: 4860 - 2442 = 62k. - Then, subtract 4860 - 2442 to get the value of 62k: 2418 = 62k. - Finally, divide both sides by 62 to solve for k: k = 2418 / 62.

3. Solving the Equation 91260-320×b=74620: - Start by subtracting 91260 from both sides of the equation: -320b = 74620 - 91260. - Then, perform the subtraction to get the value of -320b: -16640 = -320b. - Finally, divide both sides by -320 to solve for b: b = -16640 / -320.

Calculating the Solutions

Let's calculate the solutions for c, k, and b using the steps outlined above.

1. Solution for c: - c = (12750 + 900) / 210 - c = 13650 / 210 - c = 65

2. Solution for k: - k = 2418 / 62 - k ≈ 39

3. Solution for b: - b = -16640 / -320 - b = 52.

Final Solutions

The solutions to the given equations are: - c = 65 - k ≈ 39 - b = 52

These are the values that satisfy the given equations. If you have any further questions or need additional assistance, feel free to ask!
