7x-2(4x-3)=8(x+9)-30

7 x - 2 (4 x - 3) = 8 (x + 9) - 30

x = - 4

Solution steps

7 x - 2 (4 x - 3) = 8 (x + 9) - 30

Expand

- 2 (4 x - 3) : - 8 x + 6

7 x - 8 x + 6 = 8 (x + 9) - 30

Add similar elements:

7 x - 8 x = - x

- x + 6 = 8 (x + 9) - 30

Expand

8 (x + 9) - 30 : 8 x + 42

- x + 6 = 8 x + 42

Move

6

to the right side

- x = 8 x + 36

Move

8 x

to the left side

- 9 x = 36

Divide both sides by

- 9

x = - 4

F, E = F - G

- 2 (- 7 n - 8) = - 39 + 3 n

x, (x - y)^{2} = (x - y) (x - y)

c = 20 x + 15

x, 2 x + y = 200
