Question

1) 17х-3=48 2) 10х+2х-2=22 3) 3(х-5)=6х+15

Answer 1

Ответ:

1) 3, 2) 2, 3) -10

Пошаговое объяснение:

1)17х-3=48

  17х=48+3

  17х=51

  х=51/17

  х=3

2) 10х+2х-2=22

   12х=22+2

   12х=24

   х=24/12

   х=2

3) 3(х-5)=6х+15

3х-15=6х+15

3х-6х=15+15

 -3х=30

 х=30/(-3)

 х=-10

Answer 2

To solve these equations, we'll find the values of 'x' that satisfy each equation. Let's solve them one by one:

1. 17x - 3 = 48

Step 1: Add 3 to both sides to isolate the term with 'x': 17x = 48 + 3 17x = 51

Step 2: Divide both sides by 17 to solve for 'x': x = 51 / 17 x = 3

So, the solution for the first equation is x = 3.

2. 10x + 2x - 2 = 22

Step 1: Combine the 'x' terms on the left side of the equation: 12x - 2 = 22

Step 2: Add 2 to both sides to isolate the term with 'x': 12x = 22 + 2 12x = 24

Step 3: Divide both sides by 12 to solve for 'x': x = 24 / 12 x = 2

So, the solution for the second equation is x = 2.

3. 3(x - 5) = 6x + 15

Step 1: Distribute the 3 on the left side of the equation: 3x - 15 = 6x + 15

Step 2: Move the 'x' terms to one side by subtracting 3x from both sides: -15 = 6x - 3x + 15

Step 3: Combine the 'x' terms on the right side of the equation: -15 = 3x + 15

Step 4: Subtract 15 from both sides to isolate the term with 'x': -15 - 15 = 3x + 15 - 15 -30 = 3x

Step 5: Divide both sides by 3 to solve for 'x': x = -30 / 3 x = -10

So, the solution for the third equation is x = -10.

To summarize:

1. x = 3
2. x = 2
3. x = -10
