Question

1. 2 -x = x-8

2. 3+3x-1 = x+2+2x

3. 2(1+2x) = 10

4. 2(3x-2) = 2

5. -2(3x-2) = -2
​

Answer 1

1). 2-x = x-8

2+8 = x+x

10 = 2x

x = 10/2

x = 5

2). 3+3x-1 = x+2+2x

2+3x = 2+ 3x

2-2 = 3x - 3x

0= 0

Verdadero

3). 2(1+2x)=10

2+4x = 10

4x = 10-2

4x = 8

x = 8/4

x = 2

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

6x-4=2

6x= 2+4

6x = 6

x =6/6

x=1

5). -2(3x-2)=-2

-6x+4=-2

-6x= -2-4

-6x = -6

x= -6/-6

x=1
