Số số hạng là : 

      (x - 4) : 1 + 1 = x - 3 (số hạng)

Tổng là ;  (x - 3)(x - 1) 

<=> (x - 3)(x - 1) = 184 

<=> x² - 4x + 3= 184 

=> (x - 2)² - 1 = 184 

=> (x - 2)² = 185

a.

\(\left(-12\right).x-4=5^2.\left(-4\right)\)

\(\Leftrightarrow\left(-12\right).x-4=25.\left(-4\right)\)

\(\Leftrightarrow\left(-12\right).x-4=-100\)

\(\Leftrightarrow\left(-12\right).x=4-100\)

\(\Leftrightarrow\left(-12\right).x=-96\)

\(\Leftrightarrow x=\left(-96\right):\left(-12\right)\)

\(\Leftrightarrow x=8\)

b.

\(\left(-2015+184\right)-\left(84-2015\right)+\left(-200\right)\)

\(=\left(-2015+2015\right)+\left(184-84\right)+\left(-200\right)\)

\(=0+100+\left(-200\right)\)

\(=-100\)

a) (-12).x - 4 = 5².(-4)

-12x - 4 = 25.(-4)

-12x - 4 = -100

-12x = -100 + 4

-12x = -96

x = -96 : (-12)

x = 8

\(8x+32=40\Rightarrow8x=8\Rightarrow x=1\\ 216-11x=95\Rightarrow11x=121\Rightarrow x=11\\ \left(x+72\right)-184=0\Rightarrow x+72=184\Rightarrow x=112\\ 289-\left(x+167\right)=65\Rightarrow x+167=224\Rightarrow x=57\)

8 . x + 32 = 40

8 . x = 40 - 32

8 . x = 8

x = 8 : 8 

x = 1

216 -11x = 95

11x = 216 - 95

11x = 121

x = 121 : 11

x = 11

( x + 72 ) - 184 = 0

x + 72 = 0 + 184

x + 72 = 184

x = 184 - 72

x = 112

289 - ( x + 167 ) = 65

x + 167 = 289 - 65

x + 167 = 224

x = 224 - 167

x = 57

27198 : 93 =

Kết quả x = 5

\(2x\cdot\frac{2012}{18}=184\)

                \(2x=184:\frac{2012}{18}\)

                \(2x=\frac{828}{503}\)

                   \(x=\frac{828}{503}:2\)

                   \(x=\frac{414}{503}\)

93-(x+184)=-7

x+184=100

x=100-184

x=-84

   Vậy x=-84

\(\Rightarrow93-x-184=-7\)

\(\Rightarrow93-x=-7+184=177\)

\(\Rightarrow x=93-177=-64\)
