Answer 1

Решение:

-20x-15x+12x=92 (это уже прировняли к общему знаменателю)

-23x=92

x=-4

Answer 2

To solve the equation:

(-1/3)x + (-1/4)x + (1/5)x = 8/15

We need to combine the like terms on the left side and then isolate x.

Let's first find the common denominator for the fractions on the left side, which is 60.

(-20/60)x + (-15/60)x + (12/60)x = 8/15

Now, let's combine the fractions:

(-20x - 15x + 12x) / 60 = 8/15

Simplifying further:

(-23x) / 60 = 8/15

To eliminate the fractions, we can cross-multiply:

15 * (-23x) = 60 * 8

-345x = 480

Dividing both sides by -345:

x = 480 / -345

Simplifying the fraction:

x = -160/115

The final answer is x = -32/23.
