Question

А)7×+8,3+4,1+=43,82=

Answer 1

7х=43,82-(4,1+8,3)
7х=43,82-12,4
7х=31,42
х=31,42:7
х=4,48857143

Answer 2

It seems there might be a mistake in your equation. Let me clarify:

If you meant to write the equation as: 7x + 8.3 + 4.1 = 43.82

Then, to solve for x, you need to isolate it on one side of the equation. Here's the solution:

1. Subtract 8.3 and 4.1 from both sides to isolate 7x on the left side: 7x = 43.82 - 8.3 - 4.1

2. Simplify the right side: 7x = 31.42

3. Divide both sides by 7 to solve for x: x = 31.42 / 7

Calculating this: x ≈ 4.4886

So, the value of x that satisfies the equation is approximately 4.4886.
