Question

(3х +0.9) -1 1/9 =4 1/3​

Answer 1

Ответ:

x=589/270

Пошаговое объяснение:

3x + 9/10 -10/9 = 13/3

x+3/10-10/27=19/9

x+0.3=67/27

x=(670-81)/270

x=589/270

Answer 2

Let's solve the given equation step by step:

$(3x + 0.9) - \frac{1}{9} = 4 \frac{1}{3}$

First, simplify the right side of the equation:

$4 \frac{1}{3} = 4 + \frac{1}{3} = \frac{13}{3}$

Now, add $\frac{1}{9}$ to both sides of the equation to isolate the term $(3x + 0.9)$:

$3x + 0.9 = \frac{13}{3} + \frac{1}{9}$

To add these fractions, find a common denominator, which is 9:

$3x + 0.9 = \frac{39}{9} + \frac{1}{9}$ $3x + 0.9 = \frac{40}{9}$

Now, subtract 0.9 from both sides to solve for $3x$:

$3x = \frac{40}{9} - \frac{9}{10}$ $3x = \frac{400}{90} - \frac{81}{90}$ $3x = \frac{319}{90}$

Finally, divide by 3 to solve for $x$:

$x = \frac{319}{270}$
