Question

19*(0,1x+1)-(2x+1)=15

Answer 1

$19*(0,1x+1)-(2x+1)=15 \\ 1,9x+19-2x-1-15=0\\ -0,1x=-3\\x=30$

Answer 2

19 • ( 0,1х + 1 ) - ( 2х + 1 ) = 15
1,9х + 19 - 2х - 1 = 15
1,9х - 2х = 15 - 19 + 1
-0,1х = -3
х = ( -3 ) : ( -0,1 )
х = 30.
Ответ : х = 30.

Answer 3

Let's solve the equation step by step:

19*(0.1x + 1) - (2x + 1) = 15

Step 1: Distribute the 19 on the left side of the equation: 1.9x + 19 - (2x + 1) = 15

Step 2: Remove the parentheses: 1.9x + 19 - 2x - 1 = 15

Step 3: Combine like terms: (1.9x - 2x) + (19 - 1) = 15

Step 4: Simplify the terms: (-0.1x) + 18 = 15

Step 5: Isolate the variable term: Subtract 18 from both sides to move the constant term to the right side of the equation: -0.1x = 15 - 18

Step 6: Simplify the right side: -0.1x = -3

Step 7: Solve for x: Divide both sides by -0.1 to solve for x: x = -3 / -0.1

Step 8: Final answer: x = 30

So the solution to the equation is x = 30.
