Question

3х+17х+120+34х+12=240​

Answer 1

Ответ:2

Решение: 3x+17x+34x+120+12=240

3x+17x+34x+132=240

3x+17x+34x=240-132

3x+17x+34x=108

20x+34x=108

54x=108

x=108/54

x=2

Answer 2

To solve the equation 3x + 17x + 120 + 34x + 12 = 240, we can combine like terms and isolate the variable x. Here's how:

First, let's combine the x terms on the left side of the equation:

3x + 17x + 34x = 54x

Now, let's combine the constant terms on the left side of the equation:

120 + 12 = 132

Now, the equation becomes:

54x + 132 = 240

To isolate the variable x, we need to move the constant term to the right side of the equation by subtracting 132 from both sides:

54x = 240 - 132 54x = 108

Finally, we can solve for x by dividing both sides of the equation by 54:

x = 108 / 54 x = 2

Therefore, the solution to the equation 3x + 17x + 120 + 34x + 12 = 240 is x = 2.
