5x-4(2x-7)=13

5 x - 4 (2 x - 7) = 13

x = 5

Solution steps

5 x - 4 (2 x - 7) = 13

Expand

- 4 (2 x - 7) : - 8 x + 28

5 x - 8 x + 28 = 13

Add similar elements:

5 x - 8 x = - 3 x

- 3 x + 28 = 13

Move

28

to the right side

- 3 x = - 15

Divide both sides by

- 3

x = 5

- 7 n + 2 (9 n + 3) \geq 4 n + 10 - 1

19 + 13 x = 32

(i)^{4}

x^{3} - 2 x - 1

\frac{x + 32}{x + 6} \leq 3
