Question

3,9+(7,1-x)=4,5 3*(0,3-1,5)=3,6

Answer 1

А во втором корень какой?

Answer 2

To solve the equations, let's start by simplifying each equation step by step:

Equation 1: 3,9 + (7,1 - x) = 4,5

Let's remove the parentheses first:

3,9 + 7,1 - x = 4,5

Next, let's combine like terms:

11 - x = 4,5

To isolate x, we'll subtract 11 from both sides:

• x = 4,5 - 11

Simplifying further:

• x = -6,5

Now, let's solve the second equation:

Equation 2: 3 * (0,3 - 1,5) = 3,6

Start by simplifying the expression inside the parentheses:

3 * (-1,2) = 3,6

Now, multiply:

-3,6 = 3,6

The equation is not true. This means there is no solution that satisfies this equation.

To summarize the solutions:

For Equation 1: x = -6,5 For Equation 2: There is no solution.
