Question

3-(4-5x)=-2(x+14)+6​

Answer 1

Ответ:

x = -3

Пошаговое объяснение:

3-(4-5x)=-2(x+14)+6

3-4+5x=-2x-28+6

5x+2x=-28+6-3+4

7x = -21

x= -21 / 7

x = -3

проверка:

3-(4-5·(-3)) = -2 (-3+14)+6

3-(19) = -2 · 11 + 6

-16 = --16

Answer 2

3-(4-5x)=-2(x+14)+6

3-4+5x=-2x-28+6

5x+2x=-28+6-3+4

7x=-21

x=-21:7

x=-3

Ответ:x=-3

Answer 3

To solve the equation, we'll start by simplifying both sides and then isolate the variable (x) on one side. Let's go step by step:

1. Distribute the -2 on the right side: -2(x+14) = -2x - 28

2. Now the equation becomes: 3 - (4 - 5x) = -2x - 28 + 6

3. Simplify the expression inside the parentheses: 3 - 4 + 5x = -2x - 22

4. Combine like terms on both sides of the equation: -1 + 5x = -2x - 22

5. Get all the x terms on one side by adding 2x to both sides: 5x + 2x = -22 + 1

6. Combine the x terms: 7x = -21

7. Finally, solve for x by dividing both sides by 7: x = -21 / 7

8. Simplify the result: x = -3

So, the solution to the equation is x = -3.
