Question

Решите 17х - 8 = 20х + 7​

Answer 1

17x-8=20x+7

17x-20x=7+8

-3x=15

x= 15/(-3)

x=-5

Как-то так

Answer 2

17x - 8 = 20x + 7

17x - 20x = 7 +8

-3x = 15

-x = 5

x= -5

Answer 3

To solve the equation 17x - 8 = 20x + 7, we need to isolate the variable x on one side of the equation. Here's how we can do it:

Step 1: Move all the terms containing x to one side of the equation and the constant terms to the other side.

Starting equation: 17x - 8 = 20x + 7

Move 20x to the left side by subtracting 20x from both sides: 17x - 20x - 8 = 20x - 20x + 7

Simplify: -3x - 8 = 7

Step 2: Move the constant term to the opposite side of the equation by adding 8 to both sides:

-3x - 8 + 8 = 7 + 8

Simplify: -3x = 15

Step 3: Isolate x by dividing both sides of the equation by -3:

-3x / -3 = 15 / -3

Simplify: x = -5

So, the solution to the equation is x = -5.
