Question

3,2(1-2х)=0,7(3х-1,5)

Answer 1

Ответ:

3,2(1-2х)=0,7(3х-1,5)

3,2-6,4х=2,1х-1,05

-6,4х-2,1х=-1,05-3,2

-8,5х=-4,25

х=-4,25:(-8,5)

х=0,5

Answer 2

Let's solve this equation together! First, let's distribute the numbers on both sides:

$3 \cdot 2 \cdot (1 - 2x) = 0.7 \cdot (3x - 1.5)$

Simplify both sides step by step. On the left side:

$6 \cdot (1 - 2x)$

And on the right side:

$0.7 \cdot 3x - 0.7 \cdot 1.5$

Now, simplify further:

$6 - 12x = 2.1x - 1.05$

Let's get all the x terms on one side and the constant terms on the other:

$6 + 1.05 = 2.1x + 12x$

Combine like terms:

$7.05 = 14.1x$

Now, solve for x:

$x = \frac{7.05}{14.1}$

Simplify the fraction:

$x = 0.5$

So, the solution to the equation is $x = 0.5$.
