x-4(-x+5)=10

x - 4 (- x + 5) = 10

x = 6

Solution steps

x - 4 (- x + 5) = 10

Expand

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

x + 4 x - 20 = 10

Add similar elements:

x + 4 x = 5 x

5 x - 20 = 10

Move

20

to the right side

5 x = 30

Divide both sides by

5

x = 6

2 x = 50

9 x + 2 = 6

2 - 1

5 x + 1 \leq 11

6 x^{2} = - x + 35
