\(36:x=-4\\ \Rightarrow x=36:\left(-4\right)\\ \Rightarrow x=-9\)
\(36:x=-4\\ \Rightarrow x=36:\left(-4\right)\\ \Rightarrow x=-9\)
a. 219 - 7(x + 1) = 100 b. ( 3x - 6).3 = 36 c. 716 - (x - 143) = 659
d. 30 - [4(x - 2) + 15] = 3 e. [(8x - 12) : 4].33 = 36

1, 8 x 9 x 11 + 36 x 2 x 53 + 4 x 18 x 36
2, 1 + 2 + 4 + 8 + ... + 8192
2x - 36 = 46 : 43
5x+ 11= 36
[36 x 4 - 4 (82 - 7.11)2] : 4 - 20220
tính nhanh : a ) 2 x 31 x 12 + 4 x 6 x 42 + 8 x 27 x 3 b ) 36 x 28 + 36 x 82 + 64 x 69 + 64 x 41
4 x ( x + 3 )-2 x X= 36
-1/4-3/4÷x=11/36
\(t\text{ìm}x\left(\frac{36}{1\cdot3\cdot5}+\frac{36}{3\cdot5\cdot7}+.....+\frac{36}{25\cdot27\cdot29}\right)\cdot x=\frac{4}{25}\)

a ) ( x - 5 ) x 4 = 36
b) ( 48 - x ) x 2 = 14
c) ( 2 x X - 3 ) x 5 = 4
d) 1 + 3 + 5 +..........+ X = 36
e) 1 + 2 + 3 + ...........+ X = 55 + 6 +.....+ 2X = 110
