Answer 1

Ответ:

Пошаговое объяснение:

-3(-4х+1 3/5)=3,4х-6,5​

12х-4.8=3.4х-6.5

12х-3.4х=4.8-6.5

8.6х=-1.7

х=-1.7:8.6

х=-17/10*5/43

x=-17/86

Answer 2

Ответ:

3/4 : х = 1 1/5 : 1 1/3; 1 1/5 х = 3/4 * 4/3; 6/5 х = 1; х=5/6

Answer 3

Let's solve the given equation step-by-step:

-3(-4x + 1 3/5) = 3(4x - 6 5/10)

First, let's simplify the expressions inside the parentheses:

-3(-4x + 8/5) = 3(4x - 13/2)

Now distribute the -3 and 3 to each term inside the parentheses:

12x - 3(8/5) = 12x - 3(13/2)

Next, simplify the expressions on both sides:

12x - 24/5 = 12x - 39/2

Now, let's get all the terms involving x on one side and constants on the other side:

12x - 12x = 39/2 - 24/5

The x terms cancel out:

0 = (39/2) - (24/5)

To combine the fractions, find a common denominator (in this case, it's 10):

0 = (39/2)(5/5) - (24/5)(2/2)

0 = (195/10) - (48/10)

Now, subtract the fractions:

0 = (195 - 48) / 10

0 = 147 / 10

Finally, the equation simplifies to:

0 = 14.7

Since 0 is not equal to 14.7, the equation has no solution. This means that there is no value of x that satisfies the original equation.
