Can someone me with i really appreciate ! i did one of them already. ( if the first one is wrong can someone as well correct me? ? ) answer !

the answer to your questions are below

Step-by-step explanation:

1.-

          x = 3x - 60

        3x - x = 60

            2x = 60

             x = 30

            A = 30

2.-  

        - x + 26 = 2x - 10

       2x + x = 26 + 10

       3x = 36

        x = 36/3

        x = 12

        D =  2(12) - 10

        D = 24 - 10

        D = 14

3.-

    5x + 10 = 7x - 12

   7x - 5x = 10 + 12

          2x = 22

          x = 22/2

          x = 11

4.-   4x + 7 = 5(x - 4)

      4x + 7 = 5x - 20

      5x - 4x = 7 + 20

            x = 27

5.- 6(x - 2) = 3x + 30

    6x - 12 = 3x + 30

    6x - 3x = 30 + 12

           3x = 42

           x = 14

 DHG = 6(14 - 2)

DHG = 6(12)

DHG = 72

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

it is x equals 3   plese mark me really need it
