Question

Tentukan himpunan penyesuaian persamaan berikut !
a. |x-2|=6
b. |3x-5|=7
c. |2x-2|+|3x-8|=5

Answer 1

A. |x-2|=6
x-2 = 6
x = 6+2
x = 8

x-2 = -6
x = -6+2
x = -4

Answer 2

B. |3x - 5| = 7

3x - 5 = 7
3x = 7 + 5
3x = 12
x = 12 / 3
x = 4

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

HP {-2/3, 4}

maaf kalau salah...
