Question

2x + 3 = x - 6; z+4-3=2z 5 - 3y =4-2y​

Answer 1

Ответ:

1)2х+3=х-6

2х-х= - 6-3

Х= - 9

2)z+4-3=2z

z-2z=3-4

-z= - 1

z=1

3)5-3y=4-2y

-3y+2y=4-5

-y= - 1

y=1

Answer 3

Let's solve each of these equations step by step:

1. 2x + 3 = x - 6: To solve for x, you want to isolate x on one side of the equation. Start by subtracting x from both sides: 2x - x + 3 = x - x - 6

   This simplifies to: x + 3 = -6

   Now, subtract 3 from both sides to isolate x: x + 3 - 3 = -6 - 3

   x = -9

   So, the solution is x = -9.

2. z + 4 - 3 = 2z: To solve for z, begin by moving all terms involving z to one side of the equation and constants to the other side: z - 2z = -4 + 3

   Simplify: -z = -1

   Now, divide both sides by -1 to isolate z: (-z) / (-1) = (-1) / (-1)

   z = 1

   So, the solution is z = 1.

3. 5 - 3y = 4 - 2y: To solve for y, start by moving all terms involving y to one side and constants to the other side: -3y + 2y = 4 - 5

   Simplify: -y = -1

   Divide both sides by -1 to isolate y: (-y) / (-1) = (-1) / (-1)

   y = 1

   So, the solution is y = 1.
