x-(x+1)/2 =3

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

x = 7

Solution steps

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

Multiply both sides by

2

2 x - (x + 1) = 6

Expand

2 x - (x + 1) : x - 1

x - 1 = 6

Move

1

to the right side

x = 7

20 y^{2} - 5 x^{2}

\frac{1}{9} x^{4} + 4 x^{2} + 36

8 x^{5} y^{3} z^{3} + 60 x^{3} y^{6} z - 4 x^{8} y^{4}

(\frac{1}{2})^{4} \cdot (\frac{5}{2})^{- 2}

- 2 (x - 1) (4 - x) \leq 0
