Question

-3 (2,1m-1)×4,8=6,7m+94=44,9

Answer 1

1)-6,3m+3*4,8=6,7м+94=44,9
2)-6,3м+14,4-6,7м=94-44,9
3)13м=49,1-14,4
4)13м=34,7
5)м≈2,669

Answer 2

It seems like you have written an equation. Let me try to understand and solve it step by step:

The equation you provided is: -3(2m+1) × 4.8 = 6.7m + 94 = 44.9

However, there seems to be an issue with the equation as it contains two equal signs (=). Equations typically have just one equal sign. I'll assume you meant:

-3(2m+1) × 4.8 = 6.7m + 94

Let's solve it:

Step 1: Distribute the -3 across the parentheses -3 × 2m + (-3) × 1 × 4.8 = 6.7m + 94

Simplify: -6m - 4.8 = 6.7m + 94

Step 2: Move the variables (terms with m) to one side of the equation and the constants (numbers without m) to the other side.

Add 6m to both sides: -6m + 6m - 4.8 = 6.7m + 6m + 94

Simplify: -4.8 = 12.7m + 94

Step 3: Move the constant to the other side by subtracting 94 from both sides: -4.8 - 94 = 12.7m + 94 - 94

Simplify: -98.8 = 12.7m

Step 4: Solve for m by dividing both sides by 12.7: m = -98.8 / 12.7

Simplify (rounded to two decimal places): m ≈ -7.78

So the solution to the equation is approximately m = -7.78.
