Question

H)
$9x - \frac{10}{5} = \frac{5}{2} x + 2(x + 7)$

Answer 1

Boa tarde 

9x - 10/5 = 5x/2 + 2*(x + 7)

9x - 2 = 5x/2 + 2x + 14 

7x - 5x/2 = 16
14x - 5x = 32
9x = 32

x = 32/9 

Answer 2

Vamos lá

9x – 10/5 = 5/2x + 2 ( x + 7 )

9x - 2 = 5/2 x + 2x + 14

18 - 4 = 5x + 4x + 28

18x - 4 = 9x + 28

18x - 9x = 28 + 4

9x = 32

x = 32/9
