Question

-2x-7=-4x ggggggggggggggggg​

Answer 1

-2x-7=-4x

-2х + 4х = 7

2х = 7

х = 7 : 2

х = 3,5

Answer 2

To solve the equation -2x - 7 = -4x, you can follow these steps:

1. First, simplify the equation by adding 4x to both sides of the equation to get all the x terms on one side:

-2x + 4x - 7 = -4x + 4x

This simplifies to:

2x - 7 = 0

2. Now, add 7 to both sides of the equation to isolate the 2x term:

2x - 7 + 7 = 0 + 7

This simplifies to:

2x = 7

3. Finally, divide both sides by 2 to solve for x:

(2x) / 2 = 7 / 2

x = 7/2

So, the solution to the equation -2x - 7 = -4x is x = 7/2.
