Answer 1

Ответ:

7

Объяснение:

Раскрываем скобки: 20x-80-51+34x=58+3'3x

Складываем или вычитаем подобные слагаемые: 54x-131=58+3'3x

Переносим подобные к подобным с противоположным знаком через равно: 54x-3'3x=58+131

Выполняем действия: 54x-27x=189

27x=189

x=7

Answer 2

Let's simplify the left-hand side of the equation first:

20(x-4) - 17(3-2x) = 20x - 80 - 51 + 34x (distributing the 20 and -17) = 54x - 131

Now we can rewrite the equation as:

54x - 131 = 58 + 33x

Next, we'll isolate the variable terms (terms containing x) on one side of the equation and the constant terms on the other side. We can do this by subtracting 33x from both sides and adding 131 to both sides:

54x - 33x = 58 + 131

Simplifying:

21x = 189

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

x = 9

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