Question

1) x-2/7=35 2) 2/3а+а-1,6=2

Answer 1

Ответ:

Пошаговое объяснение:

1)

x-2/7=35

х = 35 - 2/7

х= 34 7/7 - 2/7

х= 34 5/7

2)

2/3а+а-1/6=2

1 2/3а = 2 + 1/6

5/3а = 2 1/6

5/3а= 13/6

а= 13/6 : 5/3

а= 13/6 * 3/6

а= 39/36

а= 13/12

Answer 2

Let's solve both of these equations:

1. $x - \frac{2}{7} = 35$

To isolate $x$, we'll get rid of the $\frac{2}{7}$ on the left side by adding it to both sides of the equation:

$x - \frac{2}{7} + \frac{2}{7} = 35 + \frac{2}{7}$

This simplifies to:

$x = 35 + \frac{2}{7}$

Now, you can add 35 and $\frac{2}{7}$ to find the value of $x$.

2. $\frac{2}{3}a + a - 1.6 = 2$

First, let's combine the like terms on the left side of the equation. $\frac{2}{3}a$ and $a$ have a common denominator of 3, so we can add them:

$\frac{2}{3}a + \frac{3}{3}a - 1.6 = 2$

This simplifies to:

$\frac{5}{3}a - 1.6 = 2$

Now, to isolate $a$, we'll add 1.6 to both sides of the equation:

$\frac{5}{3}a - 1.6 + 1.6 = 2 + 1.6$

This simplifies to:

$\frac{5}{3}a = 3.6$

To solve for $a$, you can multiply both sides by $\frac{3}{5}$ to isolate (a:

$a = 3.6 \times \frac{3}{5}$

Now, calculate $a$ by performing the multiplication.
