Question

8x-4(x+8)=8
1/2(2-4x)+2x=13
3(5x+5)=2(4x-1)+3
Simplify the equation and tell me what solutions they are.(infinite, no,or one solution)

Answer 1

Answer:

1. x=10 2. x=3 3. x=-2 *all one solution*

Step-by-step explanation:

8x-4(x+8)=8

8x-4x-32=8

4x-32=8

    +32   +32

4x=40

x=10

___________

1/2(2-4x)+2x=13

1-2x+2x=13

 +2x  +2x

x=3

____________

3(5x+5)=2(4x-1)+3

15x+15=8x-2+3

-8x        -8x

7x+15=-2+3

7x+15=1

    -15     -15

7x=-14

x=-2
