Question

Найдите корень уровнения: 1) 12х-1= 11х+7 2) -2(х-3)= 1-4хпожалуйста!!! это сор!!!!!​

Answer 1

В первом уравнение один корень:
Х=8
Во втором уравнение также один корень, я его сразу перевела в десятичную дробь:
Х= -2,5

Answer 2

Equation 1: 12x - 1 = 11x + 7

To find the root of the equation 12x - 1 = 11x + 7, we need to isolate the variable x on one side of the equation. Here's how we can solve it step by step:

Step 1: Combine like terms 12x - 11x = 7 + 1 x = 8

Therefore, the root of the equation 12x - 1 = 11x + 7 is x = 8.

Equation 2: -2(x - 3) = 1 - 4x

To find the root of the equation -2(x - 3) = 1 - 4x, we can follow these steps:

Step 1: Distribute the -2 on the left side of the equation -2x + 6 = 1 - 4x

Step 2: Combine like terms -2x + 4x = 1 - 6 2x = -5

Step 3: Divide both sides by 2 to solve for x x = -5/2

Therefore, the root of the equation -2(x - 3) = 1 - 4x is x = -5/2.
