Persamaan linear satu variabel
1.) 9y - 15 = 8y
y = ?
2.) 8/p - 2/3p = 13/6
p = ?
3.) x/3 + x-2/4 = 3
x = ?
4.) y + 4 / 4 - 3y-9/7 = 1/2
y = ?
5.) 1/4 (x -10) = 2/3 x-5
x = ?

y = 15
2. Samakan penyebut dulu utk 3p nya, menjadi :
24/3p - 2/3p = 13/6
22/3p = 13/6 (lalu kali silang)
39p = 132
p = 3,38 (saya kurang yakin sama jawaban yg ini, hehe)
3. x/3 + 3x/3 = 12/4 + 2/4
4x/3 = 14/4
4x = 14/12
x = 7/24
4. y-3y = 1/2 + 9/7 - 1
-2y = 7/14 + 18/14 + 14/14
-2y = 1/14
y = -1/28
5. 1/4x - 10/4 = 2/3x - 5
1/4x - 2/3x = -5 + 10/4
-5/12x = -20/4 + 10/4
x = -10/4 x -12/5
x = 120/20
x = 60
