3 Quita paréntesis y resuelve. a) 6(x + 1) – 4x = 5x – 9 b)18x – 13 = 8 – 4(3x – 1) c) 3x + 5(2x ... 9 8 15 = 3x 8 x = 5 b) 18x – 13 = 8 – 12x + 4 8 30x = 25 8 x = 5 6 2
[tex]x = 20 - 6 \\ x = 14 \\ \\ [/tex]
[tex]5 + x = 8 \\ x = 8 - 5 \\ x = 3[/tex]
[tex]4x = 12 \\ x = 12 \div 4 \\ x = 3[/tex]
[tex]4 + x = 20 \\ x = 20 - 4 \\ x = 16[/tex]
[tex]x \div 12 = 10 \\ x = 10 \times 12 \\ x = 120[/tex]
[tex]x - 8 = 15 \\ x = 15 + 8 \\ x = 23[/tex]
