3, tim x, biet ;
a,\(3x\left[12x-4\right]-9x\left[4x-3\right]=30\)
b,\(x\left[5-2x\right]+2x\left[x-1\right]=15\)
tìm x,biết: a,3x(12x-4)-9x(4x-3)=30
Tìm x, biết: 3x(12x – 4) – 9x(4x – 3) = 30
Tìm X a) 3x . ( 12x-4) - 9x . (4x-3)= 30 b) 6 . ( 2x+1) - 5 . ( X-2) = 10
3x (12x -4 )- 9x (4x-3)= 30 . tìm x
Tìm x :
3x(12x - 4) - 9x(4x - 3) = 30
3X(12X-4) - 9X(4X-3)=30
Tìm X ?
Tìm x biết:
3x(12x-4)-9x(4x-3)=30
Tìm x, biết :
a) 3x.(12x - 4) - 9x.(4x - 3) = 30
b) x.(5 - 2x) + 2x.( x - 1) = 15
