Question

Решитt уравнение: 12-3(2х+5)= 2(9-5х)+31

Answer 1

12-3(2х+5)= 2(9-5х)+31

12-6х-15=18-10х+31

-6х-3=-10х+49

4х=52

х=13

Answer 2

To solve the equation, we need to find the value of the variable "х" that makes the equation true. Let's simplify and solve the equation step by step:

Given equation: 12 - 3(2х + 5) = 2(9 - 5х) + 31

Step 1: Distribute the multiplication: 12 - 6х - 15 = 18 - 10х + 31

Step 2: Combine like terms on both sides of the equation: -6х - 3 = -10х + 49

Step 3: Get all the "х" terms on one side of the equation and the constant terms on the other side: -6х + 10х = 49 + 3

Step 4: Combine "х" terms: 4х = 52

Step 5: Isolate "х" by dividing both sides by 4: х = 52 / 4

Step 6: Simplify: х = 13

So, the solution to the equation is х = 13.
