Question

Tentukan persamaan nilai mutlak tersebut

A. |2x+2| = |3x-1|
B. |x-2| = |3x+2|
C. |x+3| = |2x-3|
D. |4x+3| = |2x-1|
E. |5x+1| =|2x-2|

Answer 1

1.2x+2=3x-1

2x-3x=-1-2

-x=-3

2.x-2=3x+2

x-3x=2-2

-2x=0

x=-2

3.x+3=2x-3

x-2x=-3-3

-x=-6

4.4x+3=2x-1

4x-2x=-1-3

2x=-4

x=-2

5.5x+1=2x-1

5x-2x=-1-1

3x=-2

x=-2/3

Maaf kalau salah :)
