Tentukan nilai X dari persamaan berikut A. X-3=5 B. 2X-8= -2+4X C. 8-1/2X=5 bantu jawab pake cara

a.
x - 3 = 5
x = 5 + 3
x = 8

b.
2x - 8 = -2 + 4x
2x - 4x = -2 + 8
-2x = 6
x = 6 ÷ (-2)
x = -3

c.
8 - [tex] \frac{1}{2} [/tex]x = 5
- [tex] \frac{1}{2} [/tex]x = 5 - 8
- [tex] \frac{1}{2} [/tex]x = -3
[tex] \frac{1}{2} [/tex]x = 3
x = 3 ÷ [tex] \frac{1}{2} [/tex]
x = 3 × 2
x = 6

a. x -3 = 5
x-3+3=5+3
x= 8

b. 2x-8= -2+4x
2x-4x = -2+8
-2x = 6
x= -3

c. 8-1/2x = 5
8-1 = 5*2x
7. = 10x
7/10 = x
