Answer 1

Ответ:

6(1,5 – 2,5x) = 10,5 - 1,5(x + 2x).

9-15х=10,5-1,5*3х

9-15х=10,5-9

10,5х=1,5

х= -1/7

Answer 3

Let's solve the given equation step by step:

6(1.5 - 2.5x) = 10.5 - 1.5(x + 2x)

First, distribute the 6 on the left side:

9 - 15x = 10.5 - 1.5(3x)

Now distribute the -1.5 on the right side:

9 - 15x = 10.5 - 4.5x

Now, let's move all the x terms to one side of the equation:

-15x + 4.5x = 10.5 - 9

Combine the x terms:

-10.5x = 1.5

Now, divide both sides by -10.5 to solve for x:

x = 1.5 / -10.5

x = -0.142857...

So, the solution to the equation is approximately x = -0.142857...
