Answer 1

Х-3-3х+4=15
-2х+1=15
-2х=15-1
-2х=14
х=-7
ответ: -7

Answer 2

х-3-3х+4-15=0
-2х-14=0
х=-14/2
х=-7

Answer 3

To solve the equation (х-3)-(3х-4)=15, we can follow these steps:

Step 1: Distribute the negative sign to the terms inside the parentheses on the left side of the equation: х - 3 - 3х + 4 = 15

Step 2: Combine like terms: -2х + 1 = 15

Step 3: Move the constant term to the right side by subtracting 1 from both sides: -2х = 15 - 1 -2х = 14

Step 4: Divide both sides of the equation by -2 to isolate х: х = 14 / -2 х = -7

Therefore, the solution to the equation (х-3)-(3х-4)=15 is х = -7.
