Question

Чему равно значение выражения 1.7x-(0.2x+2y) если 4y-3x=6?

Answer 1

Ответ:

1.7х - (0.2х+2у)= 1.7х-0.2х-2у = 1.5х - 2у = ( 3х-4у) = -0.5 (4у-3х)=-0.5*6= - 3

Ответ: -3

Answer 2

Calculating the Value of the Expression

To calculate the value of the expression 1.7x - (0.2x + 2y) when 4y - 3x = 6, we can follow these steps:

1. First, we need to simplify the expression by combining like terms. 2. Then, we can substitute the value of 4y - 3x with 6 and solve for the value of the expression.

Let's proceed with these steps.

Simplifying the Expression

The given expression is 1.7x - (0.2x + 2y). To simplify this, we can distribute the negative sign inside the parentheses and combine like terms:

1.7x - 0.2x - 2y

This simplifies to:

1.5x - 2y

Substituting the Given Equation

Now that we have simplified the expression, we can substitute the given equation 4y - 3x = 6 into the simplified expression 1.5x - 2y.

We can rearrange the equation 4y - 3x = 6 to solve for y in terms of x:

4y = 3x + 6

y = (3x + 6)/4

Calculating the Value

Now, we can substitute the expression for y into the simplified expression 1.5x - 2y:

1.5x - 2((3x + 6)/4)

Solving this expression will give us the value of the original expression 1.7x - (0.2x + 2y) when 4y - 3x = 6.
