11x-3x=12-20

11 x - 3 x = 12 - 20

x = - 1

Solution steps

11 x - 3 x = 12 - 20

Add similar elements:

11 x - 3 x = 8 x

8 x = 12 - 20

Subtract the numbers:

12 - 20 = - 8

8 x = - 8

Divide both sides by

8

x = - 1

x, lo g_{10} (3 z + 7) = x - 3

- 4 x + \frac{4 - x}{4} = 4

x + 3 = 12 - 8 x

\frac{k}{9} - 1 = 10

\frac{11}{9} b = \frac{7}{5}
