Answer 1

Вот, вроде бы правильно. 4 хз как решить))

Answer 2

Let's solve each equation step by step:

1. $3(2x-1) = 362(6-4x)$

First, distribute on both sides:

$6x - 3 = 2172 - 1448x$

Next, move the variable terms to one side and the constant terms to the other side:

$6x + 1448x = 2172 + 3$

Combine like terms:

$1454x = 2175$

Finally, solve for $x$:

$x = \frac{2175}{1454}$

2. $-7 = -3(2-x) + 5 - 2.4(3-1.5x) + 3.5$

First, distribute on both sides:

$-7 = -6 + 3x + 5 - 7.2 + 3.6x + 3.5$

Combine like terms:

$-7 = 8.6x - 4.7$

Move the constant term to the other side:

$8.6x = -7 + 4.7$

$8.6x = -2.3$

Finally, solve for $x$:

$x = \frac{-2.3}{8.6}$

3. $2\left(4.5x-2\right)-2.4x-\frac{1}{3}+\frac{2-x}{2}= \frac{1}{6}$

First, distribute on both sides:

$9x - 4 - 2.4x - \frac{1}{3} + \frac{2 - x}{2} = \frac{1}{6}$

Combine like terms:

$9x - 2.4x - \frac{1}{3} + \frac{2 - x}{2} = \frac{1}{6} + 4$

$6.6x - \frac{1}{3} + \frac{2 - x}{2} = \frac{25}{6}$

Next, find a common denominator for the fractions:

$6.6x - \frac{2}{6} + \frac{6 - 3x}{6} = \frac{25}{6}$

Combine the fractions:

$6.6x + \frac{4 - 3x}{6} = \frac{25}{6}$

Move the fractional term to the other side:

$6.6x = \frac{25}{6} - \frac{4 - 3x}{6}$

$6.6x = \frac{25}{6} - \frac{4}{6} + \frac{3x}{6}$

$6.6x = \frac{21 + 3x}{6}$

Now, cross-multiply:

$6.6x \cdot 6 = 21 + 3x$

$39.6x = 21 + 3x$

Move the variable terms to one side and the constant terms to the other side:

$39.6x - 3x = 21$

Combine like terms:

$36.6x = 21$

Finally, solve for $x$:

$x = \frac{21}{36.6}$

After simplifying the last equation, you should be able to solve for $x$.
