3x-4(2x-5)=5

3 x - 4 (2 x - 5) = 5

x = 3

Solution steps

3 x - 4 (2 x - 5) = 5

Expand

- 4 (2 x - 5) : - 8 x + 20

3 x - 8 x + 20 = 5

Add similar elements:

3 x - 8 x = - 5 x

- 5 x + 20 = 5

Move

20

to the right side

- 5 x = - 15

Divide both sides by

- 5

x = 3

\frac{3}{2} \cdot 12

6 x^{2} - 6 x - 72 = 0

3 x - \frac{3}{7} = 2 \frac{1}{3}

\frac{3}{2 x} > 5

\frac{7}{n + 9} + \frac{12}{4 n + 36}
