Question

Решите уравнение: 2(12 3/5 + 2x)=-6

Answer 1

12 3/5+=12,6                                                                                                      12,6+2х=-6:2
12,6+2Х=-3
2х= -3-12,6
2х=-15,6
х=-15,6:2
х=-7,8

Answer 2

2(12+3/5+2x)=-6 First, distribute the 2 to every term inside the parentheses: 24 + 6/5 + 4x = -6 Next, combine like terms: 24 + 6/5 + 4x = -6 24 + 1.2 + 4x = -6 25.2 + 4x = -6 Subtract 25.2 from both sides: 4x = -6 - 25.2 4x = -31.2 Divide by 4: x = -31.2 / 4 x = -7.8

So the solution to the equation is x = -7.8
