Question

2,7+1,9икс =2икс + 1,5 ​

Answer 1

2,7+1,9х=2х+1,5;

1,9х-2х=1,5-2,7;

-0,1х=-1,2;

х=-1,2:(-0,1);

х=12

Ответ: 12

Answer 2

To solve the equation, let's remove the decimal points by multiplying both sides of the equation by 10:

(2,7 + 1,9x) * 10 = (2x + 1,5) * 10

27 + 19x = 20x + 15

Now, let's simplify the equation by moving all the terms containing "x" to one side:

19x - 20x = 15 - 27

-x = -12

To isolate "x," we'll multiply both sides of the equation by -1:

x = 12

Therefore, the solution to the equation is x = 12.
