Terus 5|3x-1|-13=17

Answer 1

Verified answer

•
2|x + 3| = 7
|x + 3| = 7/2

x + 3 = 7/2 atau x + 3 = -7/2
x = 1/2 atau x = -13/2

HP = {1/2 , -13/2}

•
-3|-8 - x| = -9
-8 - x = 3 atau -8 - x = -3
x = -11 atau x = -5

HP = {-11, -5}

•
5|x - 3| - 13 = 17
|x - 3| = (17 + 13)/5
x - 3 = 6 atau x - 3 = -6
x = 9 atau x = -3

HP = {-3 , 9}
