Question

1,5x-0,78x=1,8 x=?????

Answer 1

Ответ:

1) 1,5x-0,78x=1,8

2) 0,72x=1,8

3) x=2,5

Вот и всё:)

Answer 2

Ответ:

x =0, так как если из 1.5х вычесть 0.78х, то будет 0.72х, а 0.72х=1.8х только при х=0

Пошаговое объяснение:

Answer 3

To solve for x in the equation:

1.5x - 0.78x = 1.8

You can first combine the terms on the left-hand side:

(1.5 - 0.78)x = 1.8

Now calculate the value inside the parentheses:

0.72x = 1.8

Finally, isolate x by dividing both sides of the equation by 0.72:

x = 1.8 / 0.72 x = 2.5

So, the solution for x is x = 2.5.
