4(x+5)=4x+5x

4 (x + 5) = 4 x + 5 x

x = 4

Solution steps

4 (x + 5) = 4 x + 5 x

Add similar elements:

4 x + 5 x = 9 x

4 (x + 5) = 9 x

Expand

4 (x + 5) : 4 x + 20

4 x + 20 = 9 x

Move

20

to the right side

4 x = 9 x - 20

Move

9 x

to the left side

- 5 x = - 20

Divide both sides by

- 5

x = 4

- x^{2} + 6 x + 16

15 x^{2 c + 3} - 25 x^{c + 1}

v^{2} - 7 v + 10

- 3 (- 7 x + 4) - 4 x = - 1.5 (- 5 x + 8.6) + 2 x

(3 x + 2) (- \frac{1}{2}) = - 5 x (\frac{1}{2}) - x + \frac{2}{3}
