Question

-1,2(0,4-3x)-12,7x=2,25

Answer 1

-1,2(0,4-3x)-12,7x=2,25

-0.48+3.6x-12.7x=2.25

-9.1x=2.25+0.48

-9.1x=2.73

x=2.73/(-9.1)

x=-0.3

Answer 2

Ответ:

-0,48+3,6х-12,7х=2,25

-9,1х=2,25+0,48

х=2,73:(-9,1)

х=-0,3

Answer 3

To solve the equation -1,2(0,4-3x)-12,7x=2,25, let's simplify the expression step by step:

Start by distributing the -1,2 to the terms inside the parentheses: -1,2 * 0 + 1,2 * (4-3x) - 12,7x = 2,25

Simplify the terms inside the parentheses: 0 + 1,2 * 4 - 1,2 * 3x - 12,7x = 2,25

Multiply: 4,8 - 3,6x - 12,7x = 2,25

Combine like terms by adding the x terms: -3,6x - 12,7x = 2,25 - 4,8

Simplify: -16,3x = -2,55

Divide both sides of the equation by -16,3 to solve for x: x = (-2,55) / (-16,3)

Calculate the value: x ≈ 0.1564

Therefore, the solution to the equation -1,2(0,4-3x)-12,7x=2,25 is approximately x = 0.1564.
