1. Today, she goes to Phu Quoc Island on holiday.

2. I learn English very much because I can use it to talk to you.

2 - ( -x + 4 ) = (-2) . (-3) + 4

2 - ( -x + 4 ) = 6 + 4

2 - ( -x + 4 ) = 10

          -x + 4 = 2 - 10

          -x + 4 = -8

                -x = -8 - 4

                -x = -12

    Vì -x = -12 nên x = 12.
