Question

4 (13 - 3x) - 17 = -5x;​

Answer 1

Ответ:

4(13-3х)-17 = -5х

52-12х-17 = -5х

-12х+5х = 17-52

7х = -35

х=-5

Answer 2

To solve the equation 4(13 - 3x) - 17 = -5x, you can follow these steps:

1. Distribute the 4 on the left side of the equation: 4 * 13 - 4 * 3x - 17 = -5x

2. Simplify the equation by performing the multiplications: 52 - 12x - 17 = -5x

3. Now, we can move all the terms with x to one side of the equation and the constants to the other side. To do this, add 5x to both sides: 52 - 12x - 17 + 5x = 0

4. Combine like terms on the left side of the equation: 52 - 12x + 5x - 17 = 0

5. Simplify further by adding and subtracting the coefficients of x: 52 - 7x - 17 = 0

6. Combine the constants on the left side: 35 - 7x = 0

7. Now, isolate the variable x by moving the constant term to the other side by adding 17 to both sides: 35 - 7x + 17 = 0 + 17

8. Simplify the right side: 52 - 7x = 17

9. Finally, isolate x by dividing both sides by -7: (52 - 7x)/(-7) = 17/(-7)

10. Simplify the equation to find the value of x: -7x = -17

11. Divide both sides by -7 to solve for x: x = (-17) / (-7)

Now, simplify the right side: x = 17/7

So, the solution to the equation is: x = 17/7
