Question

Решите плизз 6,3*(2-x)=-18,9

Answer 1

2-х=-18.9/6.3
-х=-3-2
х=5

Answer 2

12,6-6,3х=-18,9
-6,3х=-18,9-12,6
-6,3 х =-31,5 делим на -1
6,3х=31,5
х=5

Answer 3

Sure! Let's solve the equation step by step:

6.3 * (2 - x) = -18.9

First, let's simplify the expression inside the parentheses by subtracting x from 2:

6.3 * (2 - x) = -18.9 6.3 * 2 - 6.3x = -18.9

Now, let's isolate the variable term (the term with x) on one side of the equation by adding 6.3x to both sides:

6.3 * 2 - 6.3x = -18.9 6.3 * 2 + 6.3x = 18.9 6.3x = 18.9 - 6.3 * 2 6.3x = 6.3

Next, we can solve for x by dividing both sides by 6.3:

6.3x = 6.3 x = 1

Therefore, the solution to the equation 6.3*(2-x)=-18.9 is x = 1.
