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
