  1. Persamaan Linier SatuVariabel (PLSV)Linear Equation is One Variabel Ms. Dwi SMP AL FATH

  2. Kalimat • Matahariterbitdaritimur • benar • Jakarta ibukotapropinsijawatimur • salah • Jerukiturasanyamanis • Benar / salah • 1+3 = 4 • benar • x +5 = 10 • Benar / salah

  3. Benar • 1 dan 4 • Tertutup • (pernyataan) • Salah • 2 • Kalimat • Terbuka • Belumtentu • 3 dan 5

  4. Termasukpernyataan ( salah / benar ) ataukahkalimatterbuka? • Harisabtuhujan. • Kelincimempunyaiempat kaki. • 15 + 7 = 22 • - 4 + x = - 9 • AsmterdamIbukotanegarabelanda. • 2x – 6 = 0 • 12 – 5 + 7 = 7 + 7 • 3 x 4 : 2 = 12 : 2

  5. Persamaan Linier SatuVariabel (PLSV) Hanyaterdapatsatuvariabel Pangkatsatu Apakah PLSV ? x – 2 = 4 2x + 5 = x – 7 6y – 3 + 4x = 2 Kalimatterbukadgntanda “ = “

  6. PenyelesaianPLSV  x PenjumlahandanPengurangan x + 2 = 4 x + 2 = 4 2 x = 4 - 2 x = 2 x

  7. Penyelesaian PLDV 2x - 3 = x + 4 2x - 3 = x + 4 + 3 2x = x + 4 + 3 2x = x + 7 x 2x - x = 7 x x = 7 x x Harusdibayar 3 Utang 3

  8. Exercise ;

  9. Penyelesaian PLDV PerkaliandanPembagian 3x = 6 3x = 6 x : 3 x x x = 6 : 3 x = 2

  10. Exercise : 2x = 10 4x = -20 -5x = -30 ½ x = 4 ¼ x = -2 3x + 4 = 10 -2x – 3 = 5 4x – 2 = x + 7 x – 2 = 3x + 2
