Question

решите уравнение 15(x-2)=-(5-x)+17

Answer 1

15x-30=-5+x+17, 14x=42, x=3

Answer 2

15(x-2)=-(5-x)+17

15x-30=-5+x+17

15x-x=17-5+30

14x=42

x=42/14

x=3 

 

Answer 3

To solve the equation 15(x-2) = -(5-x) + 17, we can start by simplifying both sides of the equation and then solving for the variable x.

Expanding the equation: 15x - 30 = -5 + x + 17

Combining like terms: 15x - 30 = x + 12

Next, we can isolate the variable x on one side of the equation by performing the necessary operations:

Subtracting x from both sides: 15x - x - 30 = x - x + 12 14x - 30 = 12

Adding 30 to both sides: 14x - 30 + 30 = 12 + 30 14x = 42

Dividing both sides by 14: (14x)/14 = 42/14 x = 3

Therefore, the solution to the equation 15(x-2) = -(5-x) + 17 is x = 3.
