Question

2x-4x+2(5x-3)+7(2x-2)=4x+8

Answer 1

-2х+10х-6+14х-14=4х+8
22х-20=4х+8
22х-4х=8+20
18х=28
х=28/18
х=14/9

Answer 2

2х-4х+10х-6+14х-14=4х+8
2х-4х+10х+14х-4х=6+14+8
18х=28
Х=28:18
Х=1 5/9

Answer 3

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

1. Distribute the numbers outside the parentheses: 2x - 4x + 2(5x - 3) + 7(2x - 2) = 4x + 8

2. Perform the operations inside the parentheses: 2x - 4x + 10x - 6 + 14x - 14 = 4x + 8

3. Combine like terms on both sides of the equation: (2x - 4x + 10x + 14x) + (-6 - 14) = 4x + 8

Simplify the expressions: 22x - 20 = 4x + 8

4. Move all the x terms to one side and constant terms to the other side: 22x - 4x = 8 + 20

Simplify: 18x = 28

5. Finally, isolate x by dividing both sides by 18: x = 28 / 18

Simplify the fraction, if possible: x = 14 / 9

So, the solution to the equation is x = 14/9 or approximately x ≈ 1.5556.
