Question

18 4 6- x= - + -30 30 30​

Answer 1

Ответ:

$\frac{18x}{30} = \frac{4}{30} + \frac{6}{30} \\ \frac{18x}{30} = \frac{10}{30} \\ 18x = 10 \\ x = \frac{10}{18} = \frac{5}{9}$

Answer 2

To solve the equation, let's simplify the expression step by step:

18 / 4 - (6/30) x = (-30) / 30

First, let's simplify the fractions:

4.5 - (0.2) x = -1

Next, let's isolate the variable x by subtracting 4.5 from both sides of the equation:

4.5 - 4.5 - (0.2) x = -1 - 4.5

-0.2x = -5.5

To solve for x, we divide both sides of the equation by -0.2:

(-0.2x) / (-0.2) = (-5.5) / (-0.2)

x = 27.5

Therefore, the value of x that satisfies the equation is x = 27.5.
