Answer 2

17 х - х + 5 х =170 +19

21 х = 189

х = 189 : 21

х = 9

Проверка

17 х 9 - 9 + 5 х 9 - 19 = 170

170 = 170

17 х 9 - 9 +5 х 9 - 19 = 153 - 9 +45 - 19 = 144+45 = 19 = 189 - 19 = 170

Answer 3

To solve the given equation, combine like terms on the left side first:

17x - x + 5x - 19 = 170

Combine the x terms:

(17x - x) + (5x) - 19 = 170

Now simplify further:

16x + 5x - 19 = 170

Combine the x terms again:

21x - 19 = 170

Next, isolate the variable term (21x) by moving the constant term (-19) to the other side of the equation. You can do this by adding 19 to both sides:

21x = 170 + 19

21x = 189

Finally, solve for x by dividing both sides by 21:

x = 189 / 21

x = 9

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