5x - 3{4x - 2[4x - 3(5x - 2)]} = 5x - 12x + 6[4x - 3(5x - 2)] = -7x + 24x - 18(5x - 2) = 17x - 90x + 36 = -73x + 36 = 182
=> -73x = 182 - 36 = 146 => x = 146 : (-73) = -2
Tìm x biết :
5x-3{4x-2[4x-3(5x-2)]}=182
Tìm x , biết
5x-3{4x-2[4x-3(5x-2]}=182
Tìm x, biết:
5 x - 3 4 x - 2 [ 4 x - 3 ( 5 x - 2 ) ] = 182 .
\(5x-3\left\{4x-2\left[4x-3\left(5x-2\right)\right]\right\}=182\)
Hãy tìm x
Tìm x:
a) 4(18 - 5x) - 12(3x - 7) = 15(2x - 16) - 6(x + 14)
b) 5(3x + 5) - 4(2x - 3) = 5x + 3(2x + 12) + 1
c) 2(5x - 8) - 3(4x - 5) = 4(3x - 4) +11
d) 5x - 3{4x - 2[4x - 3(5x - 2)]} = 182
Tìm x, biết
a) 5x-3{4x-2[4x-3(5x-2)]}=182
b)(x2+2x+4).(2-x)+x.(x-3).(x+4)-x2+24=0
tìm x biết:
\(5x-3\left\{4x-\left[4x-3\left(5x-2\right)\right]\right\}=182\)
5x-3{ 4x-2 [4x-3(5x-2)]} =182
Bài 1: tìm X biết
a) 4(18-5x)-12(3x-7)=15(2x-16)-6(x+14)
b) 5(3x+5)-4(2x-3) =5x+3(2x+12)+1
c) 2(5x-8)-3(4x-5)=4(3x-4)+11
d) 5x-3{4x-2[4x-3(5x-2)]}=182
