2 (\frac{1}{2} y + \frac{7}{2}) + y = 21

y = 7

Solution steps

2 (\frac{1}{2} y + \frac{7}{2}) + y = 21

Expand

2 (\frac{1}{2} y + \frac{7}{2}) + y : 2 y + 7

2 y + 7 = 21

Move

7

to the right side

2 y = 14

Divide both sides by

2

y = 7

x - 9 = - 4 x

x^{2} - 6 x + 5 < 0

∣ x - 1 ∣ < \infty

(x + 4)^{2} - 2 x - 5 = (x - 1)^{2}

x^{2} + 3 x > 0
