Question

3*х=77*9;4*х=299+189;936:х=54-51.

Answer 1

Ответ:

3*x=77*9

3*x=693

x=693:3

x=231

4*x=299+189

4*x=488

x=122

936:x=54-51

936:x=3

x=312

Answer 2

To solve the equations, let's find the value of $x$ in each case:

1. $3x = 77 \times 9$

2. $4x = 299 + 189$

3. $\frac{936}{x} = 54 - 51$

4. $3x = 77 \times 9$

   First, calculate $77 \times 9 = 693$

   Now, divide both sides by 3 to solve for $x$:

   $x = \frac{693}{3} = 231$

5. $4x = 299 + 189$

   First, calculate $299 + 189 = 488$

   Now, divide both sides by 4 to solve for $x$:

   $x = \frac{488}{4} = 122$

6. $\frac{936}{x} = 54 - 51$

   First, calculate $54 - 51 = 3$

   Now, multiply both sides by $x$ to solve for $x$:

   $936 = 3x$

   Divide both sides by 3:

   $x = \frac{936}{3} = 312$

So, the solutions to the equations are:

1. $x = 231$
2. $x = 122$
3. $x = 312$
