2x+3(5x-7)=47

2 x + 3 (5 x - 7) = 47

x = 4

Solution steps

2 x + 3 (5 x - 7) = 47

Expand

3 (5 x - 7) : 15 x - 21

2 x + 15 x - 21 = 47

Add similar elements:

2 x + 15 x = 17 x

17 x - 21 = 47

Move

21

to the right side

17 x = 68

Divide both sides by

17

x = 4

x^{2} - 14 x + 50 = 0

(2 - x)^{2} (x - \frac{9}{2}) < 0

\frac{7}{3}

∣ 4 - 3 x ∣ \geq 8

\frac{1}{x + y i}
