[tex]x \times ( - 2) - 6 = 8 \\x \times ( - 2) = 8 + 6 \\ x \times ( - 2) = 14 \\ x = 14 \div ( - 2) \\ x = - 7[/tex]
[tex]3 \times x + 2 = - 10 \\ 3 \times x = - 10 - 2 \\ 3 \times x = - 12 \\ x = - 12 \div 3 \\ x = - 4[/tex]
[tex]x \div 4 + 9 = 3 \\ x \div 4 = 3 - 9 \\ x \div 4 = - 6 \\ x = - 6 \times 4 \\ x = - 24[/tex]
[tex] - 60 \div x - 5 = 7 \\ - 60 \div x = 7 + 5 \\ - 60 \div x = 12 \\ x = - 60 \div 12 \\ x = - 5[/tex]
[tex](x + 3) \times 4 = - 20 \\ x + 3 = - 20 \div 4 \\ x+ 3 = - 5 \\ x = - 5 - 3 \\ x = - 8[/tex]
[tex] - 36 \div (x - 1) + 7 = - 2 \\ - 36 \div (x - 1) = - 2 - 7 \\ - 36 \div (x - 1) = - 9 \\ x - 1 = - 36 \div ( - 9) \\ x - 1 = 4 \\ x = 4 + 1 \\ x = 5[/tex]
