Question

14*x+789=515+386. 62/x+38=40

Answer 1

Ответ:

Х=8;

Х =31

Пошаговое объяснение:

14х+789=515+386

14х=515+386-789

14х=112

Х=112:14

х=8

62/х+38=40

62/х=40-38

62/х=2

Х=62:2

Х=31

Answer 2

It looks like you have provided two equations:

1. $14x + 789 = 515 + 386$
2. $\frac{62}{x} + 38 = 40$

Let's solve these equations step by step:

Equation 1: $14x + 789 = 515 + 386$

Combine the constants on the right side: $14x + 789 = 901$

Subtract 789 from both sides to isolate $14x$: $14x = 901 - 789$ $14x = 112$

Now divide both sides by 14 to solve for $x$: $x = \frac{112}{14}$ $x = 8$

Equation 2: $\frac{62}{x} + 38 = 40$

Subtract 38 from both sides: $\frac{62}{x} = 2$

Now multiply both sides by $x$ to isolate the fraction: $62 = 2x$

Divide both sides by 2 to solve for $x$: $x = \frac{62}{2}$ $x = 31$

So, the solutions for the given equations are $x = 8$ and $x = 31$.
