Question

2) (1,8x - 1,9) - (2,7x - 3,7) = 2,1x

Answer 1

Ответ:

Х=0.6

Пошаговое объяснение:

1,8х-1,9-2,7х+3,7=2,1х

1,8х-2,7х-2,1х=1,9-3,7

-3х=-1,8

х=-1,8:(-3)

х=0,6

Answer 2

Let's solve the equation step by step:

(1.8x - 1.9) - (2.7x - 3.7) = 2.1x

First, distribute the negative sign on the left side of the equation:

1.8x - 1.9 - 2.7x + 3.7 = 2.1x

Now, combine like terms on both sides of the equation. Group the x terms and the constant terms separately:

(1.8x - 2.7x) + (-1.9 + 3.7) = 2.1x

Now, simplify the expressions:

-0.9x + 1.8 = 2.1x

Next, move all the x terms to one side of the equation by adding 0.9x to both sides:

-0.9x + 0.9x + 1.8 = 2.1x + 0.9x

1.8 = 3x

Now, isolate x by dividing both sides by 3:

1.8/3 = 3x/3

0.6 = x

So, the solution to the equation is:

x = 0.6
