1,4=2х

х=0.7

Answer 2

To find the solution to the equation, let's solve it step by step:

(7, 2 − 2x) − 3, 8 = 2

First, we need to simplify the expression within the parentheses:

(7 - 2x) − 3, 8 = 2

Next, let's isolate the term with the variable by moving the constant term to the other side:

(7 - 2x) = 2 + 3, 8

(7 - 2x) = 5, 8

Now, we can solve for x by isolating the variable. Let's subtract 7 from both sides:

7 - 2x - 7 = 5, 8 - 7

-2x = -1, 8

To isolate x, we divide both sides of the equation by -2:

(-2x) / -2 = (-1, 8) / -2

x = 0, 9

Therefore, the solution to the equation (7, 2 − 2x) − 3, 8 = 2 is x = 0, 9.
