Question

2,76+(48,93-х):4,2=18,86

Answer 1

2,76+(48,93-x):4,2=18,86
(48,93-x):4,2=18,86-2,76
(48,93-x):4,2=16,1
48,93-x=16,1•4,2
48,93-x=67,62
x=67,62-48,93
x=-18,71
Проверка:
2,76+(48,93-(-18,71)):4,2=18,86
2,76+(48,93+18,71):4,2=18,86
2,76+67,62:4,2=18,86
2,76+16,1=18,86
18,86=18,86
Ответ:x=-18,86

Answer 2

Ответ уравнения: -18,69

Answer 3

It looks like you have an equation that needs to be solved for the variable "x." Let's break down the equation and solve for x step by step:

Given equation: 2.76 + (48.93 - x) / 4.2 = 18.86

1. Subtract 2.76 from both sides of the equation: (48.93 - x) / 4.2 = 18.86 - 2.76 (48.93 - x) / 4.2 = 16.1

2. Multiply both sides of the equation by 4.2 to isolate (48.93 - x): 48.93 - x = 16.1 * 4.2 48.93 - x = 67.62

3. Subtract 48.93 from both sides of the equation to solve for x: -x = 67.62 - 48.93 -x = 18.69

4. Finally, multiply both sides of the equation by -1 to solve for x: x = -18.69

So, the solution for the equation is x = -18.69.
