Question

X+2/4 + 4x-7/3 - 9-x/12 = 1

Answer 1

Ответ:

Пошаговое объяснение:

3*(х+2)+4(4х-7)-(9-х)=1*12

3х+6+16х-28-9+х=12

3х+16х+х=12+9+28-6

20х=43

Х=43:20

Х=2,15

Answer 2

To solve the equation for x, let's first simplify and combine the terms on the left side of the equation:

$x + \frac{2}{4} + 4x - \frac{7}{3} - \frac{9 - x}{12} = 1$.

Simplify the fractions: $x + \frac{1}{2} + 4x - \frac{7}{3} - \frac{9}{12} + \frac{x}{12} = 1$.

Now, let's work on combining the terms: $5x + \frac{1}{2} - \frac{7}{3} - \frac{3}{4} + \frac{x}{12} = 1$.

Find a common denominator for the fractions: $5x + \frac{6x - 14 - 9 + x}{12} = 1$.

Combine the numerators of the fractions: $5x + \frac{7x - 23}{12} = 1$.

Now, clear the fraction by multiplying both sides by 12 to eliminate the fraction: $12 \cdot 5x + 7x - 23 = 12$.

Simplify: $60x + 7x - 23 = 12$.

Combine the x terms: $67x - 23 = 12$.

Add 23 to both sides: $67x = 35$.

Finally, solve for x by dividing both sides by 67: $x = \frac{35}{67}$.

So, the solution for the equation is $x = \frac{35}{67}$.
