Question

Plz help.... 2|x-3|-5=7

Answer 1

x = -3 and x = 9.

Explanation:

2|x - 3| - 5 = 7

2|x - 3| = 12

|x - 3| = 6

x - 3 = 6

x = 9

-(x - 3) = 6

-x + 3 = 6

-x = 3

x = -3

Hope this helps!

Answer 2

x=9 x=-3

Explanation:

2|x-3|-5=7

Add 5 to each side

2|x-3|-5+5=7+5

2|x-3|=12

Divide by 2

2/2|x-3|=12/2

|x-3|=6

There are two solutions to an absolute value equation, one positive and one negative

x-3 =6 x-3 = -6

Add 3 to each side

x-3+3 = 6+3 x-3+3 = -6+3

x=9 x = -3
