Question

8х-8=20-6х 4(х-3)=х+6

Answer 1

8x-8=20-6x;
8x+6x=20+8;
14x=28;
x=28:14;
x=2.

4(x-3)=x+6;
4x-12=x+6;
4x-x=12+6;
3x=18;
x=18:3;
x=6.

Answer 2

Решение:
1) 8х - 8 = 20 - 6х                    
8х + 6х = 8 + 20 
14х = 28 
х = 28 : 14
х = 2
Ответ: 2.

2) 4 · (х - 3) = х + 6
4х - 12 = х + 6
4х - х = 12 + 6
3х = 18
х = 18 : 3
х = 6
Ответ: 6.

Answer 3

Let's solve the equations step by step:

1. 8x - 8 = 20 - 6x

First, we'll combine like terms on both sides of the equation: 8x + 6x = 20 + 8

Now, add the x terms and the constants separately: 14x = 28

Now, isolate x by dividing both sides of the equation by 14: x = 28 / 14 x = 2

So, the solution for the first equation is x = 2.

2. 4(x - 3) = x + 6

First, distribute the 4 on the left side of the equation: 4x - 12 = x + 6

Next, move the x term to one side and the constant term to the other side: 4x - x = 6 + 12 3x = 18

Finally, isolate x by dividing both sides of the equation by 3: x = 18 / 3 x = 6

So, the solution for the second equation is x = 6.

To summarize:

1. x = 2
2. x = 6
