Question

1.(x+28):14=27. 2.29x-11x=504

Answer 1

1)$(x + 28) \div 14 = 27 \\ x = 350$

2)29х-11х=504

х=28

Answer 2

1)

$\dfrac{x+28}{14} = 27\ \ \ \ \Big| \cdot 14\\\\x+28 = 27\cdot 14\\\\x+28 = 378\\\\x = 378 - 28\\\\\boxed{\textbf{x = 350}}$

Ответ: 350.

2)

$29x - 11x = 504\\\\18x = 504\ \ \ \ \Big| :18\\\\\boxed{\textbf{x = 28}}$

Ответ: 28.

Answer 3

Let's solve each equation step by step:

1. (x + 28) / 14 = 27

First, we want to isolate x. To do that, we can start by multiplying both sides of the equation by 14 to get rid of the fraction:

(x + 28) / 14 * 14 = 27 * 14

This simplifies to:

x + 28 = 378

Now, we can isolate x by subtracting 28 from both sides of the equation:

x = 378 - 28 x = 350

So, the solution to the first equation is x = 350.

2. 29x - 11x = 504

In this equation, we can simplify the left side by combining like terms:

(29x - 11x) = 504

18x = 504

Now, to isolate x, we'll divide both sides by 18:

18x / 18 = 504 / 18

x = 28

So, the solution to the second equation is x = 28.
