Answer 2

Пошаговое объяснение:

x+2,5x+1,2•2,5x+x-1.6=22.4​

х+2,5х+3х+х-1,6=22,4

7,5х=24,5

х=≅3,2

Answer 3

To solve this equation, we need to simplify and combine like terms on both sides, and then isolate the variable "x" by performing inverse operations. Here are the steps:

1. Simplify and combine like terms on the left-hand side of the equation:

x + 2.5x + 1.2(2.5x) + x - 1.6 = 22.4 Simplify the terms inside the parentheses: x + 2.5x + 3x + x - 1.6 = 22.4 Combine like terms: 8.5x - 1.6 = 22.4

2. Add 1.6 to both sides of the equation to isolate the variable term on the left-hand side:

8.5x - 1.6 + 1.6 = 22.4 + 1.6 8.5x = 24

3. Divide both sides of the equation by 8.5 to solve for "x":

8.5x/8.5 = 24/8.5 x = 2.82

Therefore, the solution to the equation is x = 2.82.
