Question

3(х-1)-2(х-5)=5х-12​

Answer 1

Ответ:

4,75

Объяснение:

3(x-1)-2(x-5)=5x-12

3x-3-2x+10=5x-12

3x-2x-5x=-12-10+3

-4x=-19

x=4,75

Удачи!

Answer 2

Ответ:

x=4,74

Объяснение:

3x-3-2x+10=5x-12

3x-2x-5x=3-10-12

-4x=-19

4x=19

x=4,75

Answer 3

Let's solve the equation step-by-step:

1. Distribute the numbers outside the parentheses to the terms inside: 3(x - 1) - 2(x - 5) = 5x - 12

   Now, apply the distributive property: 3 * x - 3 * 1 - 2 * x + 2 * 5 = 5x - 12

2. Simplify the terms: 3x - 3 - 2x + 10 = 5x - 12

3. Combine like terms: (3x - 2x) + (10 - 3) = 5x - 12

   1x + 7 = 5x - 12

4. Now, get all the x terms on one side and constants on the other side. Let's subtract 1x from both sides: 1x + 7 - 1x = 5x - 12 - 1x

   7 = 4x - 12

5. Now, add 12 to both sides to isolate 4x: 7 + 12 = 4x - 12 + 12

   19 = 4x

6. Finally, divide both sides by 4 to solve for x: x = 19 / 4

So the solution to the equation is: x = 19/4 or 4.75
