Question

1) (×+6,5)-7,9=18,4. 2)(×-183, 8)×2,6=39,52

Answer 1

1) x+6.5-7.9= 18.4
x-1.4=18.4
x=18.4+1,4
x=19.8

2) 2.6x-477.88=39.59
2.6x=39.59+477.88
2.6x=517.4
x=199

Answer 2

$1)(x + 6.5) - 7.9 = 18.4 \\ x + 6.5 - 7.9 = 18.4 \\ x = 18.4 + 7.9 - 6.5 \\ x = 26.3 - 6.5 \\ x = 19.8$
$2)(x - 183.8) \times 2.6 = 39.52 \\ 2.6x - 477.88 = 39.52 \\ 2.6x = 39.52 + 477.88 \\ 2.6x = 517.4 \\ x = 517.4 \div 2.6 \\ x = 199$

I'm sorry, but I'm not sure what you are asking. It appears that you have provided two equations, but you have not stated what you would like me to do with them. Could you please clarify your question or provide more information?
