Question

17х-х+5х-19=170 Как его решить

Answer 1

17x-x+5x-19=170;

21x-19=170;

21x=170+19;

21x=189;

x=189:21;

x=9

Answer 2

17х-х+5х-19=170


21х-19=170

21х=170+19

21х=189

х=189/21

х=9 

Answer 3

To solve the equation, we need to simplify and combine the terms on the left-hand side and then isolate the variable "x." Let's proceed step by step:

1. Combine the "x" terms: 17x - x + 5x - 19 = 170

   Combine "x" terms: (17x - x + 5x) = 21x The equation now becomes: 21x - 19 = 170

2. Isolate the variable "x" on one side of the equation. To do this, we'll move the constant term (-19) to the other side by adding 19 to both sides of the equation:

   21x - 19 + 19 = 170 + 19 21x = 189

3. Finally, solve for "x" by dividing both sides by the coefficient of "x" (21):

   21x / 21 = 189 / 21 x = 9

So, the solution to the equation is x = 9.
