Question

Помогите пожалуйста Упрастите выражение; 4/9*[4 1/2y-1 1/2]-2/7*[1 1/6-3 1/2y] решите пожалуйста срочно надо!!!

Answer 1

$\frac{4}{9}\left[4\frac{1}{2}y-1\frac{1}{2}\right]-\frac{2}{7}\left[1\frac{1}{6}-3\frac{1}{2}y\right]=\\ =\frac{4}{9}\left[\frac{9}{2}y-\frac{3}{2}\right]-\frac{2}{7}\left[\frac{7}{6}-\frac{7}{2}y\right]=\\ =2y-\frac{2}{3}-\frac{1}{3}+y=3y-1$

Answer 2

Simplifying and Solving the Expression

To simplify the given expression 4/9*[4+1/2y-1+1/2]-2/7*[1+1/6-3+1/2y] and solve it, we can follow these steps:

1. Simplify the expression inside the brackets. 2. Perform the multiplication and subtraction operations.

Let's start by simplifying the expression inside the brackets.

The given expression is: 4/9*[4+1/2y-1+1/2]-2/7*[1+1/6-3+1/2y]

Simplify the expression inside the first set of brackets: 4+1/2y-1+1/2 = 3+1/2y

Simplify the expression inside the second set of brackets: 1+1/6-3+1/2y = -2+1/6+1/2y = -2+1/6+1/2y

Now, we have: 4/9*(3+1/2y)-2/7*(-2+1/6+1/2y)

Perform the multiplication and subtraction operations to simplify the expression further.

Let's calculate the expression step by step.
